The Core Store
The National Core Store houses petroleum, minerals and coal core cuttings and samples, and has fit-for-purpose viewing facilities
Companies exploring for petroleum, minerals and coal under permit in New Zealand are required to offer core cuttings and samples collected during the process of drilling and sampling to New Zealand Petroleum & Minerals.
Any material requested or accepted by the Crown is held in confidence for a period of up to five years, before becoming available for any industry member or the research community to access and sample.
All of the submitted petroleum wells have been catalogued and photographed. To view the photos of the core, cuttings or well samples, please visit our Exploration Database.
Mineral and coal core are currently undergoing the same process.
Submitting core and samples
In accordance with the relevant regulations, permit holders are required to submit core, sidewall core, and other samples collected when drilling.
Petroleum permit holders must supply well samples within 120 days of completion of drilling.
