9.50pm UPDATE - Greens co-leader Jeanette Fitzsimons has conceded her Coromandel seat to National and made a strong appeal to Labour to form a centre-left coalition with the Greens.
Though the Greens have hedged on their coalition intentions through the campaign, Jeanette Fitzsimons told her supporters tonight the party is now
ready to go into a Labour-led coalition.
She said "If any other party were to join with Labour to make the numbers up, then it would be a very very different kind of government from what we have seen in the last three years and very different from the sort of government the Greens would want to support."
Clearly if there is going to be a Government of the left then it has to include the Greens."
National's Sandra Goudie is well ahead in the seat, taken by Ms Fitzsimons from National in 1999, with Labour's Max Purnell second.
With two thirds of the votes counted, the Greens have 6.29 per cent of the vote, guaranteeing them eight seats in Parliament - one more than they did in 1999.
Ms Fitzsimons won the seat in 1999 by a slim 250 votes, but a split left vote seems to be giving National's Sandra Goudie the lead.
Coromandel had been a National seat for decades and was a key electorate in the last election as the win ensured the Green Party's presence in Parliament irrespective of its party vote result.
In Banks Peninsula Greens co-leader Rod Donald was also polling third - well behind Labour's Ruth Dyson and National's David Carter.
Despite polls having indicating increased support for the Greens, up to nine percent of the party vote, the results so far indicate they will be no better off than after the last election.
