LISTEN ABOVE AS DAMIAN LIGHT SPEAKS TO MIKE HOSKING

United Future has confirmed it's all over.

The party's board has voted unanimously to disband.

Survival was always going to be an uphill battle once then-leader Peter Dunne pulled out during the election campaign.

His replacement, Damian Light said there's an air of inevitability.

"It's quite sad and for many reasons, but sometime we had to call it day on United Future I guess. We had a really good run, 15 years, but it's time to retire the party unfortunately."

A letter sent out to members this week said the party's leadership had voted to disband after it received just 0.1 per cent of the vote in this year's general election.

The centrist party had survived on the back of an electoral deal in Ohariu between long-time leader Peter Dunne and the National Party - but Mr Dunne's resignation this year - sparked by poor poll numbers - meant it failed to return to parliament.

Light said that United Future had been having "robust discussions" about its future and that despite its successes in Parliament "it is no secret that we have struggled at election time".

"Since the election we've been investigating why - we've talked to members and non-members, those who voted for us and those that didn't.

"We know people like our policies and vision but it hasn't translated into votes. While the reasons vary, what has become clear is that United Future will not be able to achieve the significant number of votes required to break the threshold.

"This decision has not been made lightly and has been debated at length, with a motion unanimously passing at this weekend's annual general meeting in Auckland."
