What is the motherhood wage penalty in New Zealand?

New Zealand research shows that mothers who take any career break face an average wage penalty of 4.4% on return. Those who are out of paid work for more than a year face a penalty of around 8.3%. This means their hourly rate on return is lower than it would have been had they stayed in the workforce, and this gap compounds over the rest of their career.

How much does a career break cost in New Zealand?

The total opportunity cost of a career break in New Zealand depends on your salary, age, how long you take off, and your KiwiSaver contributions. It typically includes: the direct income gap during leave, a wage penalty of 4–8% on return, missed salary progression, and a KiwiSaver shortfall. For someone earning $80,000 taking two years off at age 30, the total opportunity cost in today's dollars is typically $200,000–$350,000.

How fast does your salary typically grow each year?

Lawyers, doctors and finance professionals in NZ commonly see 5–10%+ annually in their early career. The NZ-wide professional average sits around 3–4%.

How we calculate this: We use NZ-specific research from Motu Research and Stats NZ. The wage penalty on return (4.4% for any break, 8.3% for breaks over a year) is from peer-reviewed NZ labour market data. All future figures are converted back to today's dollars using 2.5% annual inflation — so the numbers are meaningful now, not in 20 years.

Fully paid by employer

Govt PPL only ($788/wk cap)

No income (self-employed / not eligible)

Some employers top up to full salary for the whole break. If that's you, your direct income gap is $0 — though the wage penalty and KiwiSaver impacts still apply.

What each year out actually costs: The first year is relatively contained — it's mostly the direct income gap. But from year two onwards, the wage penalty compounds, and missed salary progression starts to stack. Most of the long-term cost comes from years two and three, not year one.
