Green MP Kevin Hague is quitting Parliament to take on the top job at environmental organisation Forest and Bird.
The party confirmed this afternoon that Hague, the Greens' third-ranked MP, had accepted the chief executive position at Forest and Bird and would be resigning as an MP.
He will be replaced by Auckland-based candidate Barry Coates, the former executive director of Oxfam New Zealand.
Greens' co-leader Metiria Turei said the party was sorry to be losing Hague, who had "worked tirelessly and effectively" for the party.
"We will miss his passion and his wisdom," co-leader James Shaw said.
