Party president Moira Coatsworth told reporters the way the party would try to achieve the targets was through the list ranking process of the moderating committee, after it had made an assessment of which electorate seats it thought it could win.
But the starting point of selection criteria was about skills.
It was 120 years since women got the vote in New Zealand but women made up less than a third of the Parliament.
The moderating committee would operate as it had in the past by having "an equity check" after every five rankings.
Asked if men would miss out because of the target, Ms Coatsworth said "for the last 120 years, women have missed out.
"This is about getting women equity. There are lots of women with merit. It's not about merit or representation. It's about representation that includes merit.
