The response showed since 2009, between a quarter and a third of all New Year and Queen's Birthday Honour nominations had been for women, and that in 10 of the 13 honours lists, the percentage of honours awarded to women matched or surpassed the percentage of those nominated.
"This gender imbalance is unacceptable," Dr Hanlen said.
"It is time for New Zealanders to better celebrate women, as well as men, who make a difference. Women make up half our population and certainly contribute more than 37 per cent.
"This lack of recognition for women is just another sign of the gender inequality that persists in our country. 122 years on from women winning the right to vote, we are still fighting for women's paid and unpaid contributions to society to be equally recognised and valued."
