42nd New Zealand Parliament

The 42nd New Zealand Parliament was a term of the Parliament of New Zealand. Its composition was determined by the 1987 elections, and it sat until the 1990 elections.

The 42nd Parliament was the second (and final) term of the controversial fourth Labour Party government. Initially, the only other party in the 42nd Parliament was the National Party, with the Democratic Party having lost the two seats it held in the 41st Parliament. Later, a dissident Labour MP would found the NewLabour Party. Due to internal disputes within the Labour Party, there were three Prime Ministers during the 42nd Parliament: David Lange, Geoffrey Palmer, and Mike Moore.

The 42nd Parliament consisted of ninety-seven representatives. At the time, this was the highest number of representatives that Parliament had had, although it would later be exceeded. All of these representatives were chosen by single-member geographical electorates, including four special Māori electorates.
