There's a new approach to tackle New Zealand's stubborn gender pay gap.
Acting Minister for Women Louise Upston's announced a new tool businesses can voluntarily use to calculate the divide.
It replaces plans from the previous Government to make reporting mandatory.
The national pay gap is 8.6% and has typically sat around 9-10% for the past decade.
Business leader Dame Theresa Gattung told Mike Hosking that unconscious bias plays a significant role in why it exists.
She says a good chunk of the pay gap is unexplained, and doesn't just relate to women taking time out of the workforce to have children, for example.
