The date was announced by Prime Minister John Key during a press conference earlier today.
When making the announcement Mr. Key said that the elections will be about building stronger growth, building greater value for money in public services, and building a safer New Zealand.
He also ruled out any chances of his National Party making any alliances with the Winston Peters-led New Zealand First Party.
New Zealand has a Mixed Member Proportion representation (MMP) system, where individual Members are voted through a simple first-past-the-post voting system and the proportion of party representation in parliament is decided through a proportional voting system through which List MPs are selected.
The life of Parliament in New Zealand is three years. The last general elections was held in 2008.
