Greens won't rule-out supporting National

The Green Party is "highly unlikely" to support a National-led government following November's election -- but is not ruling it out.

Party delegates confirmed the Greens' post-election position at their annual meeting today, saying it was an independent party that could support a Labour-led government in the right circumstances.

"We’re more likely to support Labour on confidence and supply, and think it is highly unlikely that we could support a National government on confidence and supply, but it is on the table," Greens co-leader Metiria Turei said.

"It’s more likely we could work project-by-project with National like we do now on home insulation, tourism infrastructure and toxic site management."

Mrs Turei stressed the Party had negotiated more than $400 million worth of Green programmes with the current National-led Government.

"We are an independent political party in Parliament with a good track record of policy wins and we will continue to make gains from inside or outside Government," she said.

"We can get stuff done, and I can promise more wins with either National or Labour," Mrs Turei said.

However, the Greens would need serious gains from any confidence and supply agreement with either party.

"Our goal is to be in Government, but we might prefer to stay out of confidence and supply agreements in November, based on circumstances at the time. Government has gone badly for a lot of support parties."

Mrs Turei's co-leader, Russel Norman, yesterday announced a Greens-led government would keep it local by transferring all government banking to Kiwibank.

Dr Norman, also speaking at the party's annual meeting, called for the Government to move its accounts away from Australian-owned Westpac, which has held the contract for 22 years.

"The Green Party is serious about fixing our banking system so that we are no longer mortgage slaves to the Aussie banks," he said.

"Our government’s banking should be done by our New Zealand bank."

Dr Norman also announced today that under a Green government, the country’s state-owned energy companies would issue green energy bonds to raise capital.

The clean energy sector was booming internationally, with the solar, wind and biofuels sector worth $190 billion this year and being projected to grow to $350 billion in the next decade, he said.

"New Zealand can get a piece of that action by being focussed and strategic and building on our strengths.

"Supercharged public energy companies, partnered with bright green Kiwi entrepreneurs, funded by kiwi mums and dads with safe green energy bonds, exporting clean technology; now that is a vision for a bright future."
