The 41st Parliament was the first term of the fourth Labour Party government.

It marked the end of three terms of National Party administration under Robert Muldoon.

David Lange become Prime Minister and Roger Douglas became Minister of Finance — the economic reforms undertaken by Douglas, nicknamed Rogernomics, would prove to be a defining feature of the fourth Labour government, and were deeply unpopular with Labour's traditional support base.

The National Party, now in opposition, experienced a number of leadership disputes, replacing Muldoon first with Jim McLay and then with Jim Bolger.
