Social Development Minister Paula Bennett has reclaimed the Waitakere seat from Labour's Carmel Sepuloni by nine votes in a judicial recount.
Official confirmation is expected later today.
Ms Bennett was named the winner of the electorate on election night after the results gave her a 349-vote lead over Ms Sepuloni.
However, the National MP lost the seat in last Saturday's special vote count, which gave Ms Sepuloni an even tighter margin of 11 votes.
Ms Bennett applied for a judicial recount.
