This year's local body elections have attracted just 29 per cent of female candidates.
Figures show since the 2007 local elections the percentage of female candidates has remained static.
During this election Ms O'Leary met with two women who had decided to run and had announced their candidacy but then pulled out just before nominations opened.
"Talking to them afterwards they felt there was not a lot of information about what the job actually entails, in practical terms. Adding to that the challenge of being thrust into the public arena without that knowledge made them reconsider," she said.
"While I believe women are more inclined to get involved with local community issues and are more likely to vote (Statistics NZ media release September 19), they just aren't standing. We have to find out why - and then do some pretty serious work to change that.
"We want to connect with potential future elected women much earlier leading up to an election and having associate members will further provide those opportunities. Access and networking opportunities with elected women throughout New Zealand, receiving our newsletters and access to our events will be some of the key benefits to the new membership. We'll also be about to connect potential future leaders with currently elected women to mentor and support them into politics."
Women in Politics is a not for profit, non-partisan incorporated society, which aims to increase the number of elected women in local and central government.
