Winston Peters has refused to say whether Labour's policy of raising the pension age would be a deal breaker should New Zealand First be the kingmaker after the 2014 election.
In a speech to about 200 party faithful gathered in Palmerston North yesterday for their annual conference, he said the cost of paying NZ Super to immigrants was a more pressing threat to its affordability.
Mr Peters, a former foreign minister in a Labour-led Government, has been under sustained pressure to clarify his comment to the Herald last week that keeping the pension age at 65 would be a "bottom line" for NZ First in any post-election talks in 2014.
After his speech, Mr Peters was asked whether NZ First could work with Labour in 2014 if the larger party retained its current policy of raising the age to 67 gradually over 12 years from 2020. "The answer is no."
However, he did not categorically rule out a confidence-and-supply agreement with Labour, saying it was too early to set out NZ First's negotiating position.
