Caregiver Kristine Bartlett believes her hourly wage of $14.46 is less than what would be paid to male employees with the same or similar skills.
And she's about to test pay equality in court.
Ms Bartlett, of Lower Hutt, took TerraNova Homes and Care to the Employment Relations Authority last year alleging a breach of the 40-year-old Equal Pay Act and the Employment Relations Act.
"I don't think people really acknowledge or recognise our work and the skills that we have for the pay rate we get - it's just unfair," she said.
"It's exhausting, it's demanding and unless somebody stands up and fights, they just will not do anything and recognise how hard it is. We do it because we love it."
