Dr Sharples and fellow co-leader Tariana Turia will also get a number of other portfolios.

Mrs Turia will be Minister for the Community and Voluntary Sector, Associate Health Minister and Associate Social Development Minister.

Dr Sharples will also be Associate Education Minister and Associate Corrections Minister.

All posts are outside of Cabinet with the right to dissent on other policy issues outside portfolio areas.

National has agreed not to remove the Maori seats without the consent of Maori and a group will be set to look at constitutional issues including Maori representation.

National has also agreed to a review of the Foreshore and Seabed Act to see if it is working and whether there are any better alternatives.

The Maori Party has agreed in exchange to give National its five votes on confidence and supply issues as well as work together to promote common priorities.

Mr Key earlier announced a support deal with Act.
