The New Zealand dollar is dangerously over-valued and the Government must take action to bring it down, opposition parties say.
The dollar opened on Wednesday at 81.46 US cents, falling more than half a cent overnight after Prime Minister John Key said one-way bets on its continued strength were "not a very smart thing to do".
Labour's finance spokesman, David Parker, says trying to talk it down isn't enough.
"Our exporters are cutting jobs and shutting down because they can't compete against low overseas exchange rates. We need to take action on the dollar," he said on Wednesday.
Mr Parker says Labour's policies would work - pro-growth tax reforms to take the pressure off the dollar and a new Reserve Bank Act allowing it to focus on exports.
"It was written in a time when the main economic threat was inflation, now the threat is stagnation," he said.
NZ First leader Winston Peters says New Zealand has become a haven for "hot money" chasing high interest rates.
"This is what they call the `carry trade' where speculators shift money around from low yielding currencies and invest in higher yielding currencies," he said in a speech to the Marlborough Chamber of Commerce.
"As our dollar flits about way above tolerable levels the question is how long are New Zealanders prepared to stand by in a straightjacket or orthodoxy, paralysed from doing anything about it."
Mr Peters says his party has prepared legislation to give the Reserve Bank the flexibility it needs to promote growth, employment and exports.
