Should New Zealand introduce an option to extend Parliament's maximum term from three to four years, subject to a select committee condition and a binding referendum?
This omnibus bill would amend the Constitution Act 1986 and the Electoral Act 1993 to create a variable parliamentary term, keeping the standard three-year maximum but allowing extension to four years if a specified condition is met, with the change taking effect only after a binding referendum.
MPs’ arguments for and against the bill
Why support it
Supporters argued a four-year term would give governments a longer period of effective decision-making, since time is lost establishing a government early on and preparing for re-election late in the term.
Supporters said a longer term would reduce disruption from frequent changes of government and benefit long-term projects such as infrastructure where the cost of change is high.
Supporters noted New Zealand is an outlier internationally with its three-year term and that the bill pairs the longer term with stronger select committee scrutiny to balance the change.
Why oppose it
Opponents said using legislation to dictate the House's Standing Orders on select committee membership is unusual and effectively binds future Parliaments through the back door.
Opponents argued the conditional, variable term creates uncertainty because the length of Parliament would not be settled until a decision is made, and the referendum question would be harder to communicate than a simple three-or-four-year choice.
Opponents said the change should be considered within a broader constitutional review and alongside matters like local government terms, rather than addressed in isolation.
These are claims MPs made in Parliament’s debate — not verified facts.

This omnibus bill would let a Parliament run for up to four years instead of the usual three. It keeps three years as the standard maximum but allows a four-year term where a specified condition about the make-up of Parliament's select committees is met — broadly, giving opposition parties a fairer share on the committees that scrutinise government. The change could only take effect after a binding public referendum, because the term length is protected in the Constitution Act 1986.
The idea has a long history — voters rejected a four-year term at referendums in 1967 and 1990 — and was revived through the current governing agreement. Supporters say four years gives governments more time to develop and deliver policy; critics say New Zealand's lack of an upper house makes longer terms risky without added checks.
