Political parties on the left and right must reach agreement on how a four-year electoral term would be implemented before the issue goes to the public for discussion, otherwise the proposal will fail once again, says New Zealand First Leader Winston Peters.
Mr Peters and Green Party co-leader Metiria Turei yesterday agreed with Prime Minister John Key and Labour leader David Shearer that the country would benefit from a four-year parliamentary term but the change needed to be supported by the public via a referendum.
The proposal failed when it was put to voters in the 1967 and 1990 elections, almost 70 per cent favouring the three-year term over four years.
Mr Peters said his caucus had discussed the idea some time ago and while it had merit, the key question was whether or not a referendum on the issue was ever likely to succeed.
"The chinless wonders on each end of the political spectrum, feeling their opponents might win, inevitably go for the three-year term so you're almost beaten before you start on the referendum."
