Planning to take a detector to Tanzania? A general hobby-detecting rule covering both Mainland Tanzania and Zanzibar could not be confirmed. Their heritage laws must be considered separately. Mainland law establishes an immediate reporting duty for covered discoveries; the reviewed evidence does not establish when Zanzibar’s Ancient Monuments Preservation Act came into force. Confirm the rules for your activity and exact area before searching or recovering a target.

The rules, land by land
Anywhere: national heritage law
No verdict yetA general metal-detecting rule covering both Mainland Tanzania and Zanzibar could not be confirmed.
- On the Mainland, Antiquities Act section 11 requires a license for digging or probing for monuments or relics, removing or collecting suspected relics except for statutory protection and reporting, and searching for or collecting ethnographical objects. Section 12 imposes scientific training or experience and other qualifications.
- The captured Zanzibar Ancient Monuments Preservation Act section 14 describes a ministerial permit for research of ancient monuments by exploration, searching the earth’s surface, diving or other means, for a researcher from a recognized institution. The Act’s commencement notice has not been established, so its current operation remains unconfirmed.
- The National Museum of Tanzania publishes a treasure-investigation license template under section 13 of the Mainland Antiquities Act. The template does not establish a general hobby-detector entitlement or a Zanzibar authorization.
Digging
Research permits onlyIn Mainland Tanzania, digging or probing for monuments or relics requires an excavation license subject to scientific qualifications.
- This row covers Mainland Tanzania only. It does not establish a Zanzibar digging rule; commencement of the captured Zanzibar Ancient Monuments Preservation Act remains unconfirmed.
- Mainland Antiquities Act section 11 applies to excavation, digging or probing for monuments or relics on a person’s own land as well as elsewhere. It excepts the Director General of the National Museum of Tanzania and persons acting on their behalf.
- Section 12 requires sufficient scientific training or experience, sufficient staff and financial and other resources, and, for an excavation license, the ability to conduct or arrange proper scientific study and publication of discovered material.
- Under section 13, the license does not authorize entry or excavation without the landowner’s consent. The license may impose reporting, documentation, preservation and other conditions.
- These heritage-purpose provisions do not settle ordinary recreational digging to recover modern lost items.
What the rule says
“(a) excavate, dig or probe for monuments or relics;”
Keeping finds
No verdict yetMainland relic ownership is established, but the current operation of the reviewed Zanzibar antiquity-disposal provisions and a complete nationwide rule for other treasure or ordinary lost property remain unconfirmed.
- On the Mainland, Antiquities Act section 8 assigns discovered relics to the Republic, subject to the statutory listed-relic and preexisting institutional-holding exceptions and the Director’s power to disclaim ownership.
- The captured Zanzibar Act’s sections 25–27 state that discovered antiquities must be notified to the Authority. Under that text, once the Authority notifies the finder that an object is an antiquity, sale, destruction or removal needs its written permission. The Authority may retain a qualifying object for 90 days, or longer by agreement, and decide on return or government preservation. The Act’s commencement notice has not been established, so its current operation remains unconfirmed.
- Under that captured Zanzibar text, section 27 provides for compensation equivalent to the object’s value, with ministerial permission, or return of the object, subject to the Act. Licensed research discoveries are excluded from that compensation provision; the license schedule assigns objects found under the license to the government. These provisions share the unresolved commencement question.
- Mainland Penal Code section 258(5) and Zanzibar Penal Act section 251(5) say conversion of a lost item is not deemed fraudulent when the finder does not know the owner and reasonably believes the owner cannot be discovered. These criminal-law provisions do not themselves establish civil ownership or a finder’s treasure share.
Reporting finds
No verdict yetMainland law requires prompt reporting of covered heritage discoveries; the current operation of the captured Zanzibar reporting provisions could not be confirmed.
- On the Mainland, Antiquities Act section 10 requires a person discovering a relic, monument or reasonably suspected relic or monument outside a licensed search or excavation, and a land occupier who knows of that discovery, to report forthwith to an administrative officer, the Director of Antiquities, the Conservator or the Curator of the Museum.
- The Mainland discoverer must take reasonable protective steps and, if required, deliver a portable find to the statutory recipient on payment of delivery costs. Licensed work is subject to its license conditions, including any reporting conditions imposed under section 13.
- The captured Zanzibar Ancient Monuments Preservation Act section 25 states that any discoverer of an antiquity, including a licensed researcher, must notify the Authority forthwith. It also states that discoveries outside licensed research must be described by circumstances and exact place, and surrendered if required; a finder uncertain whether an object is an antiquity must consult the Authority forthwith. The packet does not establish the Act’s commencement under section 1.
- The captured Zanzibar Act names as recipient the Authority under section 4; its current operation remains unconfirmed. These heritage provisions do not establish a complete reporting procedure for ordinary modern lost property.
Reporting finds
Must be reportedIn Mainland Tanzania, covered heritage discoveries outside licensed searches or excavations must be reported immediately to a statutory recipient.
- On the Mainland, Antiquities Act section 10 requires a person discovering a relic, monument or reasonably suspected relic or monument outside a licensed search or excavation, and a land occupier who knows of that discovery, to report forthwith to an administrative officer, the Director of Antiquities, the Conservator or the Curator of the Museum.
- The Mainland discoverer must take reasonable protective steps and, if required, deliver a portable find to the statutory recipient on payment of delivery costs. Licensed work is subject to its license conditions, including any reporting conditions imposed under section 13.
- This reporting duty is stated for Mainland Tanzania only. It does not establish the current reporting rule in Zanzibar.
What the rule says
“and the occupier of any land who knows of any such discovery on or under such land, shall forthwith report the same to an administrative officer, the Director, the Conservator or the Curator of the Museum:”
Beaches & foreshore
No verdict yetA general beach-detecting rule for Mainland Tanzania and Zanzibar could not be confirmed.
- On the Mainland, Antiquities Act section 11 requires a license for digging or probing for monuments or relics, removing or collecting suspected relics except for statutory protection and reporting, and searching for or collecting ethnographical objects. Section 12 imposes scientific training or experience and other qualifications.
- The captured Zanzibar Ancient Monuments Preservation Act section 14 describes a ministerial permit for research of ancient monuments by exploration, searching the earth’s surface, diving or other means, for a researcher from a recognized institution. The Act’s commencement notice has not been established, so its current operation remains unconfirmed.
- In Mainland marine parks and reserves, Marine Parks and Reserves Act section 22 restricts collecting sand, minerals or aquatic substrate and destroying, defacing or removing objects, except as permitted by the Act or regulations. This protected-area provision does not cover every beach or establish a Zanzibar coastal rule.
Protected monuments
No verdict yetGeneral detector use at protected monuments could not be confirmed for both Mainland Tanzania and Zanzibar; Mainland heritage restrictions are established, while the captured Zanzibar Act’s current operation remains unconfirmed.
- On the Mainland, Antiquities Act section 5 restricts damaging or altering protected monuments, with a written-approval exception under subsection (2). Sections 11–13 separately govern licensed digging or probing for monuments and relics.
- The captured Zanzibar Act’s section 30 makes destruction, removal, injury, alteration, defacement or imperiling of a protected monument or antiquity an offense, and section 14 describes a separate permit for ancient-monument research, including surface searching. The Act’s commencement notice has not been established, so these provisions’ current operation remains unconfirmed.
National parks & nature reserves
No verdict yetA general detector rule for national parks and nature reserves across Mainland Tanzania and Zanzibar could not be confirmed.
- For Mainland national parks, National Parks Act section 23 requires an entry permit subject to its statutory exceptions. An entry permit does not by itself establish authorization to detect or recover finds.
- For Mainland marine parks and reserves, Marine Parks and Reserves Act section 22 restricts destroying, defacing or removing objects and collecting sand, minerals or aquatic substrate, except as permitted by the Act or regulations.
- Mainland heritage excavation and collection rules remain relevant to their covered activities. The captured Zanzibar Act describes ancient-monument research rules, but their current operation remains unconfirmed because commencement has not been established. The linked Mainland park statutes do not establish a Zanzibar protected-area detector rule.
State forests
No verdict yetA general forest-detecting rule for Mainland Tanzania and Zanzibar could not be confirmed; their forest-reserve laws restrict specified disturbance and removal.
- On the Mainland, Forest Act section 26 requires a concession, license or permit for listed acts in national and local-authority forest reserves, subject to its existing-right-holder exception. Listed acts include taking rocks, stones, sand, shells or soil, breaking up land for any purpose, and damaging vegetation.
- In Zanzibar, Forest Resources Management and Conservation Act section 32 restricts taking rock, sand, shells or soil, clearing land and damaging vegetation in forest reserves and areas covered by a notice of intent, unless authorized by a section 62 license or applicable community forest management agreement.
- Mainland heritage-search and excavation restrictions apply to their covered activities. The captured Zanzibar heritage Act also describes ancient-monument research controls, but its commencement remains unconfirmed. Neither forest provision establishes general permission to sweep a detector or recover modern lost items.
Private land
No verdict yetA general private-land detecting rule could not be confirmed for both Mainland Tanzania and Zanzibar; Mainland heritage licenses do not replace owner consent, and the captured Zanzibar Act’s current operation remains unconfirmed.
- On the Mainland, Antiquities Act section 11 applies to covered excavation and collection on a person’s own land as well as elsewhere. Section 13(2) says a license does not authorize entry, excavation or ethnographical search or collection without the landowner’s consent.
- The National Museum of Tanzania’s treasure-investigation license template also requires owner consent before entry or investigation.
- The captured Zanzibar Act’s section 14 describes a permit for ancient-monument research, and condition 3 of its license schedule says the license does not authorize entry, excavation or destruction of crops or residential areas without the owner’s consent. The Act’s commencement notice has not been established, so its current operation remains unconfirmed.
Even where detecting is allowed, archaeological and historic sites are protected, and you must fill every hole and follow posted rules. Always confirm the current rule with the land manager.

Mainland heritage searches and private land
The Antiquities Act requires an excavation license for digging or probing for monuments or relics, with an exception for the Director General of the National Museum of Tanzania and persons acting on their behalf. It also covers removing or collecting suspected relics, except for statutory protection and reporting, and searching for or collecting ethnographical objects. Section 12 requires sufficient scientific training or experience, staff, and financial and other resources. An excavation-license applicant must also be able to conduct or arrange proper scientific study and publication of discovered material; for a collector’s license, the ethnographical objects must be used for study or a purpose approved by the Director General. These provisions do not settle ordinary recreational detector use.
The National Museum of Tanzania publishes a treasure-investigation license template under the Act. That template does not establish a tourist or hobby-detector entitlement, a finder’s ownership share, or permission in Zanzibar. A Mainland heritage license also does not replace the landowner’s consent for the entry and activities it covers.
Zanzibar: heritage provisions with an unresolved start date
The reviewed Ancient Monuments Preservation Act provides for commencement through a ministerial notice in the Gazette. Its official catalog listing and a government project document do not establish that notice. The following describes the Act’s text; its current operation could not be confirmed.
Section 14 describes a permit for ancient-monument research, including surface searching and diving, for a researcher from a recognized institution. The license schedule also requires owner consent for the entry and activities it specifies. This research framework does not establish general recreational detecting permission.
Protected monuments, beaches, and parks
On the Mainland, Antiquities Act section 5 restricts damaging or altering covered monuments, with a written-approval exception. Zanzibar’s reviewed Act also contains offenses for damaging or removing protected monuments or antiquities, subject to the commencement uncertainty above. General detector use at protected monuments remains unconfirmed.
A general beach-detecting rule could not be confirmed for either territory. In Mainland marine parks and reserves, section 22 of the Marine Parks and Reserves Act restricts collecting sand, minerals, or aquatic substrate and destroying, defacing, or removing objects, except as permitted by the Act or regulations. Those restrictions concern marine protected areas; they do not establish a rule for every beach or for Zanzibar.
Mainland national parks require an entry permit, subject to statutory exceptions. Entry permission alone does not establish permission to detect or recover finds. A complete detector rule for national parks and nature reserves across Mainland Tanzania and Zanzibar could not be confirmed.
Forest reserves
Mainland Forest Act section 26 requires a concession, license, or permit for listed activities in national and local-authority forest reserves, subject to its exception for existing right-holders exercising an established right. Listed activities include taking rocks, sand, shells, or soil, breaking up land, and damaging vegetation.
Zanzibar’s Forest Resources Management and Conservation Act lists restrictions on taking rock, sand, shells, or soil, clearing land, and damaging vegetation in forest reserves and areas covered by a notice of intent. It provides exceptions through a section 62 license or an applicable community forest management agreement. The reviewed copy is not a current consolidated edition. A general detector-use and recovery rule for all public forests in both territories remains unconfirmed.
Reporting a discovery
On the Mainland, a person who discovers a relic, monument, or reasonably suspected relic or monument outside a licensed search or excavation must report it immediately. A land occupier who knows of that discovery must also report it. Section 10 names an administrative officer, the Director of Antiquities, the Conservator, or the Curator of the Museum as recipients.
The Mainland discoverer must take reasonable protective steps and, if required, deliver a portable find to the statutory recipient on payment of delivery costs. Licensed work is subject to its license conditions, including any reporting conditions imposed under section 13.
Zanzibar’s reviewed Act says discoveries of antiquities must be reported immediately to the Authority under that Act, including discoveries by licensed researchers. It also provides for consultation when a finder is uncertain whether an object is an antiquity. Because commencement was not established, a current nationwide reporting rule remains unconfirmed. That uncertainty does not change the separately established Mainland reporting duty.
Keeping a find
On the Mainland, discovered relics belong to the Republic under section 8 of the Antiquities Act, subject to the listed-relic and preexisting institutional-holding exceptions and the Director’s power to disclaim ownership.
Zanzibar’s reviewed Act describes a different process: once the Authority notifies the finder that an object is an antiquity, sale, destruction, or removal needs written permission. The Act provides for retention and a decision on return or government preservation. Its current operation remains unconfirmed.
A complete rule for keeping other treasure or ordinary lost property in both territories could not be confirmed. The reviewed Mainland and Zanzibar criminal provisions about lost items do not themselves establish a finder’s civil ownership or treasure share.

Frequently Asked Questions
- Can I detect on a beach in Tanzania?
- A general beach-detecting rule could not be confirmed for Mainland Tanzania or Zanzibar. Mainland marine parks and reserves have specific restrictions on collecting material and removing objects. Check the rules for the particular beach and planned recovery method before starting.
- Is a treasure-investigation license a hobby-detecting permit?
- The National Museum of Tanzania’s published template does not establish general hobby-detector eligibility. The Mainland Antiquities Act sets qualifications for the excavation and collection licenses it covers, and owner consent is separate. The template does not authorize activity in Zanzibar.
- Must I report a possible relic?
- On the Mainland, covered discoveries outside licensed searches or excavations must be reported immediately to an administrative officer, the Director of Antiquities, the Conservator, or the Curator of the Museum. Licensed work follows its license conditions. Zanzibar’s reviewed Act also contains reporting provisions, but its commencement was not established, so the current Zanzibar duty could not be confirmed.
- Does the landowner’s consent settle the rules?
- A general private-land detecting rule could not be confirmed across both territories. On the Mainland, the Antiquities Act’s covered excavation and collection rules apply on a person’s own land as well as elsewhere; the heritage license does not replace owner consent. Zanzibar’s reviewed research-license text also specifies owner consent, subject to the unresolved commencement question.
