The motherhood penalty and ways to work around it

7 May 2025
Reading time: 8 minutes

Stakeholder Specialist Natalie Palmer didn’t realise she’d been affected by the motherhood penalty until it had already happened. “I didn’t really know what it was until I started working at Sorted. Then I joined the dots and realised – thats me! 

When even the most onto it women aren’t fully aware of the barriers taking time off work to parent can create, you’d be forgiven for finding yourself in the same boat. And as we give you the rundown of what the motherhood penalty means and steps you can take to mitigate it, it’s important to note that this isn’t something for only mums to grapple with – we can all work together to flip the script. Given a 2021 report by Westpac suggests New Zealand’s economy could increase by an average of $1.5 billion every year if we shared the load more equally at home, change will be to everyone’s benefit. 

What is the motherhood penalty anyway? 

The motherhood penalty is a global problem that highlights the challenges working mums face because of deep-rooted biases. It’s about the financial and career setbacks that can result from taking time out of work to care for kids, including: 

  • Less income 

  • Paused or reduced contributions to investments like KiwiSaver 

  • Opportunities to upskill put on hold 

  • Unfair treatment, such as: 

    • Hiring biases
    • Assumptions about abilities or productivity
    • Being demoted
    • Fewer promotions, which also means fewer women in leadership roles.

 

Gender inequality in the workplace – and at home  

Aspects of the motherhood penalty can apply to men, too, but it might be the mother of all injustices that generally speaking, whereas fathers can be seen as more responsible and committed to their careers after having children, and may even be promoted or experience pay increases (to help them ‘bring home the bacon’), mothers get left holding the baby – and carrying the burden.

Natalie took 10 months of parental leave after her and husband Jamie’s daughter, Eden, was born, returned to part-time employment for a year after that, moved into full-time positions for a while to help them save for a house, then reverted to part-time work when Eden started school before going full-time again. She and Jamie have been together since their early 20s and divide both responsibilities and money equally, yet rather than considering the long-term earning and career implications, when they were planning to get pregnant, their conversation focused on whose hand would rock the cradle and who would provide financially.   

“It was an easy decision for me to stay at home with the baby, says Natalie, who now works at Te Ara Ahunga Ora Retirement Commission, which runs Sorted. “It’s how I always pictured it happening, and it made sense given Jamie earned more than me, plus he received commission and bonuses, so him taking time off would have penalised us more financially. 

Natalie felt “extremely blessed” that they could afford for her to stay home with Eden, and lucky to step into a well-paid part-time role when her maternity leave was up, but my god, it was hard. This is when I started to feel the motherhood penalty without realising that’s what it was. Because I was part-time, Id usually be the one to take time off when Eden picked up one of the many daycare bugs, which made it difficult for me to give work my all, because I was always worried about that dreaded phone call from daycare. I couldn't think about my career or future self in any way I was just trying to get by. 

Since Natalie and Jamie both emptied their KiwiSaver accounts to buy a house after Eden was born, Natalie wasnt subjected to the inequality in KiwiSaver contributions that can occur between the paid versus the unpaid parent or the part- or full-time salary, but still, she says, it was a shock for me to realise the motherhood penalty applied to me in other ways.  

Looking back now, I can see that we put a lot of emphasis on Jamie progressing his career and earning the money, whereas my work was just about doing something to contribute to the household while being flexible around Eden. It was a stressful time, but I just saw it as something we – or I! –  had to get through. Now I realise I might not have had to.  

“Jamie’s workplace at the time had zero flexibility, and in hindsight, we should have considered alternative employment on his end to allow for that, so it didn’t all fall on me. Now he is in a new role that means he’s able to work from home when Eden’s sick, do school drop-offs, attend the sports days, etc, so it feels much more like a 50/50 split in terms of childcare. 

Practical steps for your parental leave planning 

  1. If you learn one thing, make it how compounding interest works its magic on investments like your KiwiSaver fund via this short video on how to get the gains. Finding ways to get as many dollars as you can continuing to work for you both is key. Even small amounts put away regularly can result in thousands more in your pocket over time.  

  2. Plot out an equitable plan with your partner or co-parent that will benefit you both. Could sharing the parental leave be a suitable option? Check out our Planning for a family guide, and use our budget and goal planners, and KiwiSaver and retirement calculators to get on track for the life you want.  

  3. Have proactive, open conversations with your higher-ups to voice concerns and how to avoid them, discuss your career goals, agree on expectations and confirm your commitment to the team. Aim to keep the lines of communication as open as possible. 

  4. Understand your organisation’s policies around parental leave, so you’re clear as to what you’re entitled to. Under New Zealand law, you can’t be dismissed from your job for going on parental leave, and as long as you give the proper notice, your employer must keep it open for you unless it’s defined as a key position or your role becomes redundant due to restructuring. 

  5. Keep up your KiwiSaver contributions. You can choose whether you want to have voluntary KiwiSaver contributions deducted from your parental leave payments, and thanks to a law change that came into effect on 1 July 2024, if you do contribute, Inland Revenue will also make employer contributions of 3%. At the very least, if possible, it’s advantageous to ensure you’re both contributing the minimum $1042.86 between 1 July and 30 June each year in order to qualify for the maximum government KiwiSaver contribution of $521.43. (If you don’t reach that threshold, you’ll still receive 50c from the government for every dollar you contribute.) 
    If you’re taking unpaid leave, perhaps your partner could contribute to your KiwiSaver as well as their own. “Having learned how much harder women are hit financially by divorce, as well as my career progression, I would have considered the financial consequences before taking unpaid time off work,” says Natalie. If Jamie’s KiwiSaver had continued to grow without any gaps in contributions, he would have been much better off than me if we’d split.” 

  6. When you’re ready to resume work, talk to your employer about ways to make your transition easier, such as a phased plan that sees you gradually increase your hours. 
    Of course, our ability to grow our savings and investments isn’t just about continuing to work but also maximising our earnings – and job satisfaction – by progressing professionally. If you are looking for a new position that pays better, Natalie has this tip: “Through different jobs, I learned the importance of working for the right people, and started asking the tough questions upfront, like: What’s the flexible working policy,  and how does the team respond to parents taking sick leave for their kids? Up until that point, I would have never asked those questions in an interview because I thought it would reduce the likelihood of me getting the role, but now I don’t want it if they don’t answer correctly.” 

Empower yourself to make motherhood work for you 

Despite the setbacks, Natalie’s story has a happy ending – and yours can too. “Working with a super-supportive team showed me I could take the next step in my career while also being flexible for my family, she says.  

Today, I’m in a good place professionally and my most important job will always be being a mum, so I’d pick that over a dollar figure any day but I know now that when we’re young and about to have a baby, we need to understand the effect the choices we make now can have on our career and financial future.”
