The 43rd New Zealand Parliament was a term of the Parliament of New Zealand. Its composition was determined by the 1990 elections, and it sat until the 1993 elections. The 43rd Parliament saw the beginning of the fourth National Party government, with the Labour Party failing to win a third term in office. The 43rd Parliament was heavily dominated by National, which controlled nearly seventy percent of the seats. Only one minor party, Jim Anderton's NewLabour, was present at the beginning of the 43rd Parliament. Later, NewLabour would join with several unrepresented parties to form the Alliance, which would gain two additional seats when two National MPs defected. Another National MP, Winston Peters, would also break away from his party, becoming an independent.
