Both National and Labour put their chances of forming a coalition government with New Zealand First at 50-50 - but National's revealed they're also interested in talking to the Greens.
Their leaders are waiting for a call from Winston Peters so talks can start, but so far he hasn't picked up the phone.
National's deputy leader Paula Bennett, appearing on Newshub's The AM Show today, said she couldn't pick it.
"On Saturday night I was on the euphoria of 58 seats and here we go - but now we've got some work to do... it could go any way. Until you've had those conversations you can't pick it."
Bennett floated the possibility of National and the Greens talking to each other about forming a government - they could have a majority with the Greens' seven seats.
She believed her personal relationship with the Greens was "great" and that they respected her work on climate change.
"We'd quite like to talk to them," she said.
"But I don't think they are up for it, they say that's not what they stood (campaigned) on."
Labour's deputy leader Kelvin Davis confirmed there hadn't been any contact.
"Right now it's 50-50," he said when he was asked what the chances were of Labour forming a government.
"No conversations have started yet."
Greens' leader James Shaw has all but ruled out talking to National.
Peters has said there can't be any serious negotiations until special votes have been counted and the results released on October 7.
