The minister of Finance (Māori: Minita mo nga Moni), originally known as colonial treasurer, is a minister and the head of the New Zealand Treasury, responsible for producing an annual New Zealand budget outlining the government's proposed expenditure.

There are currently three associate minister roles held by Chris Bishop, David Seymour, and Shane Jones.

According to Parliament's Standing Orders, the Minister of Finance may veto any parliamentary bill which would have a significant impact on the government's budget plans.

The Minister of Finance supervises the Treasury, which is the government's primary advisor on matters of economic and financial policy.

[6][7] At times, the appointment of associate ministers was intended to temper the reform ambitions of Roger Douglas.

The position of Treasurer was senior to that of the Minister of Finance, and was created as part of the coalition agreement between the National Party and New Zealand First.

After the change of government in 1999, both positions were held concurrently by Michael Cullen before they were combined into the old Minister of Finance portfolio in 2002.
