Ten people will contest the Botany by-election for the parliamentary seat left vacant by the resignation of National MP Pansy Wong.
Mrs Wong resigned in December last year over the misuse of her international travel subsidy.
The National Party candidate, Auckland Councillor Jami-Lee Ross, is tipped as the front-runner to replace her.
Labour's Michael Wood and ACT's Lyn Murphy are the only other candidates from parties already in Parliament.
There are three independents and four candidates from single issue parties such as the Join Australia Movement Party.
The by-election takes place on 5 March; advance voting begins on 16 February.
