The 2017 update to the Cabinet Manual has been released by the Department of the Prime Minister.

The Cabinet Manual is the primary authority on the conduct of Cabinet government in New Zealand. It documents Cabinet's procedure and provides authoritative guidance for Ministers, their offices, and those working within government. Successive governments have endorsed the Cabinet Manual as a principled and effective basis on which to operate.

Each iteration of the Cabinet Manual records incremental changes in the constitutional and administrative arrangements of executive government.

In the 2017 edition, the guidance on Ministers and the House of Representatives has been updated, the text reflects amendments to legislation governing the operation of the State sector, and changes to Cabinet-decision making procedures and processes have been incorporated.
