Paula Bennett has held the Waitakere seat with a 349 majority, but with more than 3400 special votes to be counted, she is not celebrating just yet.
On election night, the lead swung between the National incumbent and Labour list MP Carmel Sepuloni.
Yesterday, Ms Bennett told the Herald it was one of the most nerve-racking evenings of her life.
"It jumped around and I suppose the West is really dependent on which booth is coming in because it's so diverse ... It was definitely an up-and-down evening," she said. "I feel like I've won it and I do think there is enough of a buffer there but no, I'm not cracking open the champagne yet."
Ms Sepuloni spent Saturday night with about 100 friends, relatives and supporters as the results came in.
