Act is back in Parliament, thanks to the voters of Epsom endorsing candidate John Banks but last night the party had only enough votes for one MP, meaning leader Don Brash dipped out on a seat - and later signalled his resignation.
Brash said he would meet the Act board, probably tomorrow, and would tender his resignation as leader.
He had mixed feelings about the election result: "I'm delighted that John Banks is into Epsom, of course, but I'm disappointed we didn't get more of the party vote because we had some very, very good candidates."
Brash's leadership had been a hot topic during the campaign, with New Zealand First leader Winston Peters claiming that, during their notorious "cup of tea" conversation, John Banks had told Prime Minister John Key that list candidate Catherine Isaac should be the Act leader.
Isaac, recently widowed after the death of second husband Roger Kerr, was in Wellington last night, while the main gathering of party faithful was at Barry Court in Parnell.
