A day of working for free isn't usually an opportunity to celebrate - but today women around the country will do just that.
‘Work for Free' Day symbolically represents the day women start working for free for the rest of the year due to unequal pay.
In New Zealand the average woman earns 13.1 per cent less than the average man, meaning that from now until the end of the year, Kiwi women are not being paid for their work.
Research commissioned by the previous government shows that 80 per cent of the gender pay gap is "unexplained" and thus due to bias against women and jobs considered "women's work".
Some honouring the day include the PSA who will join Labour and Greens ministers for a special celebration at Parliament.
"We want to thank the new Labour-led government for its strong stance on equal pay," says PSA assistant national secretary Kerry Davies.
"They've already ditched the deeply flawed bill introduced by the previous government, and the Minister for Women wants to end the public sector pay gap by 2020.
"If unions continue to work with government and business - as they did in the Joint Working Group on Equal Pay Principles - we can get this done."
The ministers will receive a limited-edition poster thanking them for their commitment to the issue and encouraging them to commit to policies that will end gender pay discrimination.
Tauranga-based Labour MP Angie Warren-Clark, who was unable to join the festivities today due to a caucus meeting, says it's an issue she believes needs to change.
“I think it's been recognised that the inequality has not been due to the fact that we don't put ourselves forward, that there aren't those opportunities for us or that we aren't skilled, but instead it is due to bias and sexism.
“Hopefully men will stop and participate in the day's festivities too,” she says. “If we as a society think it is okay to pay women less then what does that say about us as a nation?”
The Council of Trade Unions says politicians have the power to make today a happier date for New Zealand women.
"The 13 per cent gender pay imbalance means the boss is in essence getting free labour out of women in paid work from today until January 1, 2018.
“Maori women collectively started working for free on October 8. Pasifika women are effectively unpaid for over a quarter of the year - their employers started taking free labour, on average, from September 21.
"Our law already says that taking this unpaid labour from women is illegal, and the free ride is about to end.
“We have three parties in government now who have committed to putting the agreed equal pay principles into the current law and not creating additional hurdles for women. This will create a swift and clear legal pathway for women to claim the pay that's rightfully theirs."
