Review of the Crown Minerals Act 1991

The Government is carrying out a review of the Crown Minerals Act 1991.

This is to ensure the Act’s settings contribute to mining that responsibly balances environmental, social, and economic considerations and meets the evolving needs of New Zealand’s society.

The review is one of the actions the Government is undertaking to realise the vision in the 10-year Resource Strategy of a world-leading environmentally and socially responsible minerals and petroleum sector that delivers affordable and secure resources, for the benefit of current and future New Zealanders.

Minerals and petroleum resource strategy

Public consultation on a discussion document, exploring a wide range of issues and options, concluded at the end of January 2020, and 167 submissions were received.

Decommissioning of petroleum infrastructure and other changes

The first set of changes the Government is looking to make relates to strengthening the regulatory framework for decommissioning petroleum infrastructure under the Crown Minerals Act 1991 (CMA). 

These changes are proposed to be made through the Crown Minerals (Decommissioning and Other Matters) Bill (the Bill), introduced on 23 June 2021.

The Bill includes other changes that are not specific to decommissioning and will apply to all current and future petroleum permit and licence holders and mineral permit holders.
