The Real Cost of a New Baby in NZ and the Cover New Parents Need

What a new baby actually costs in the first year, how paid parental leave leaves an income gap, and the life, income and KiwiSaver moves new parents commonly weigh up. 2026.

A new baby changes your money in two directions at once. Costs go up, and for most families one income drops for a while. The numbers themselves are manageable for most people, but they tend to arrive together, just as your household is most stretched. Planning for both sides early takes a lot of the pressure off.

This guide walks through what a baby tends to cost in the first year in New Zealand, how paid parental leave works and where it leaves a gap, and the life, income and KiwiSaver questions new parents commonly think through.

TL;DR: Government-funded paid parental leave runs for up to 26 weeks ¹ and is capped at $788.66 gross a week ², so anyone earning more than that faces an income gap on top of higher household costs. A baby is also the point many people first weigh up life and income cover, and a reduced-income year can shrink the KiwiSaver government contribution ⁴⁵. This is general information, not advice.

What does a new baby actually cost in the first year in NZ?

There is no single national figure for this, and any estimate depends heavily on the choices you make: whether you buy new or second-hand, breastfeed or use formula, and what childcare looks like once leave ends. So treat the numbers below as a Smiths Financial estimate to help you frame a budget, not a precise forecast.

It helps to split the cost into two parts. There are one-off setup costs before and around the birth, and there are ongoing monthly costs that continue through the year.

The setup costs are the visible ones, and they are also where second-hand and hand-me-downs make the biggest difference. The ongoing costs are smaller individually but steady. Childcare, where it applies, is often the largest single item, but it usually starts later in the year and varies so much by hours and location that it is best priced for your own situation rather than averaged.

The more important point for planning is that these costs land at the same time as the income change in the next section.

How does paid parental leave work, and where's the income gap?

Government-funded paid parental leave is paid to an eligible primary carer for one continuous period of up to 26 weeks, roughly six months ¹. It is administered by Inland Revenue, and you can be an employee or self-employed.

The part that catches people out is the cap. The payment is set at your normal pay up to a maximum, and for the period from 1 July 2025 to 30 June 2026 that maximum is $788.66 gross a week ². For an eligible self-employed person there is also a minimum payment of $235.00 gross a week ³.

So the gap depends on what you normally earn:

• If you earn at or below the cap, paid parental leave broadly replaces your usual weekly pay (up to that ceiling).
• If you earn above the cap, you receive the maximum, and the difference between that and your normal pay is the income gap you carry for up to six months.

A simple way to picture the first year is to put the rising costs and the falling income side by side.

It is also worth knowing what does not fill this gap. ACC replaces up to 80% of your income, but only when you cannot work because of an injury ⁷. It does not cover pregnancy, childbirth, illness or simply choosing to take time off with a baby. So ACC is not a backstop for the parental-leave income gap; that gap is something families plan for themselves.

How families bridge a temporary income drop, with savings, a buffer, or income cover, is something we cover in income protection versus a savings buffer.

Why does a baby change how much life and income cover you need?

Before children, if your income stopped you mostly had yourself to support. Once someone depends on you, the question changes from "could I manage?" to "could my family manage without my income?" That is why a new baby is the point at which many people first look seriously at life and income cover.

Two types of cover tend to come up:

• Life cover pays a lump sum if you die, which can clear debt such as a mortgage and provide for dependants. With a young child, the period you would most want this cover is often long, sometimes 20 years or more, until children are independent.
• Income protection pays a monthly benefit if you cannot work for an extended period because of illness or injury. Because ACC only covers injury ⁷, income protection is how some people cover the illness side, which a young family is rarely positioned to absorb.

The amount of cover people in this situation consider is shaped by their mortgage and other debts, the number and ages of dependants, the surviving partner's income, and any cover already held through work or KiwiSaver providers. There is no single correct figure, and more cover is not automatically better, since it also costs more in premiums.

A couple of things are worth being clear-eyed about. Cover is not free of conditions: whether a claim is paid depends on the policy terms, exclusions, stand-down periods, underwriting and your disclosure, so the wording matters as much as the headline sum. And the right structure, who owns the policy, how the lump sum is paid, how the term is set, is part of the value an adviser adds. We go through that in how an adviser structures life cover, and the wider picture for parents is in life cover for parents.

Should one parent's reduced income change your KiwiSaver plan?

A year on reduced income does not usually call for a dramatic change to your KiwiSaver, but it is worth understanding two effects.

First, while you are on paid parental leave, the payment is treated as income but KiwiSaver employer contributions generally stop, because you are not receiving normal salary or wages from your employer. You can still choose to contribute from your parental-leave payments, but it is not automatic in the way payroll deductions are.

Second, the year you contribute less is the year your own balance grows more slowly, both from smaller contributions and, for higher earners, from missing employer contributions. Over a 30- or 40-year horizon a single lighter year is a small dent, not a disaster. It is the kind of thing some people choose to top up later when income returns, rather than something to stress about during the leave itself.

What this is not is a reason to chase a different fund to "make up" the gap. Switching to a higher-risk fund purely to recover a lighter contribution year mixes up two separate decisions, your contribution level and your risk profile, and adds volatility at a time when many families value stability. Fund choice should follow your time horizon and comfort with ups and downs, and KiwiSaver returns are not guaranteed and can fall as well as rise.

Does the government contribution still apply on parental leave?

Yes, but the maths is worth understanding, because a reduced-income year can quietly cost you part of it.

The KiwiSaver government contribution is 25 cents for every $1 you contribute, up to an annual maximum of $260.72 for the contribution year ⁴. To receive that full amount you need to put in at least $1,042.86 of your own money between 1 July and 30 June ⁵. Employer contributions do not count toward that threshold, only your own do ⁵.

That is the catch for a parent on leave. If your own contributions for the year fall below $1,042.86, your top-up is scaled back to 25 cents per dollar of what you actually put in. A family with one parent on six months of reduced income can easily slip under the line without realising.

This contribution was halved at Budget 2025, from a maximum of $521.43 for the year ended 30 June 2025 ¹⁰ down to the current $260.72 ⁴. There is also an income cap: from 1 July 2025, members with taxable income over $180,000 a year no longer receive the government contribution at all ⁶.

One option some people use during a reduced-income year is to make a voluntary lump-sum contribution before 30 June to reach the $1,042.86 line and secure the full $260.72, if their budget allows. Whether that makes sense depends on your cash flow, and it is a personal decision. We unpack the change in more detail in the KiwiSaver government contribution cut.

What cover should you sort before the baby arrives versus after?

Timing matters for one practical reason: most life and income cover is underwritten, meaning the insurer assesses your health before offering terms. Pregnancy itself, and some pregnancy-related conditions, can lead an insurer to defer a decision or apply temporary terms. That is a reason some parents look at cover before or early in a pregnancy rather than leaving it until the busy newborn weeks.

A rough way to think about sequence:

• Before / early on: review existing life and income cover while health is straightforward to assess, and check what you already hold through work or a mortgage.
• Around the birth: confirm your budget for the leave period and the income gap, and make sure any cover already in place still reflects your situation.
• After things settle: revisit cover amounts as your mortgage, childcare costs and the second income picture become clearer, and decide whether to top up KiwiSaver contributions for the year.

None of this is urgent in the sense of a deadline, and it is general information rather than a prescription. The point is simply that some steps are easier earlier, so it is worth knowing the order rather than leaving everything to the last few weeks.

How do you budget for childcare and one income?

The transition that surprises people is not always the leave period itself, it is the months around it: one income for up to six months, then in many cases childcare costs starting as the second parent returns to work.

A few practical habits tend to help:

• Build a buffer before the birth. Saving toward the expected income gap while two incomes are still coming in is far easier than catching up later.
• Price your own childcare early. Costs vary widely by hours and region, so a realistic local figure beats a national average. Some support may be available through Work and Income depending on circumstances, which is worth checking directly.
• Re-budget for the "return to work" point, not just the leave. For many families the tighter month is when childcare starts, not when the baby arrives.
• Keep KiwiSaver and cover on the list. They are easy to defer, but a quick review now is cheaper than a gap discovered later.

Sorted's budgeting tools at sorted.org.nz are a good free starting point for mapping this out, and an adviser can help size the cover and the buffer around your actual numbers.

Frequently asked questions

How much does a baby cost in the first year in NZ?

There is no official national figure, and it depends heavily on your choices. As a budgeting guide, one-off setup costs (cot, car seat, pram, clothing) often run from around $1,500 to $4,000 or more, with ongoing monthly costs of roughly $200 to $500. Childcare, where it applies, usually starts later in the year and varies widely. These are Smiths Financial estimates to help you plan, not a precise forecast, and your costs will differ.

How long is paid parental leave and how much does it pay?

Government-funded paid parental leave is paid for one continuous period of up to 26 weeks for an eligible primary carer ¹. It is set at your usual pay up to a maximum of $788.66 gross a week for the period 1 July 2025 to 30 June 2026 ². Eligible self-employed people have a minimum payment of $235.00 gross a week ³. If you normally earn more than the cap, the difference is an income gap you plan for yourself.

Does ACC cover me if I take time off for a baby?

No. ACC weekly compensation replaces up to 80% of your income, but only when you cannot work because of an injury ⁷. It does not cover pregnancy, childbirth, illness or simply taking leave with a baby. That is one reason some families look at income protection, which can cover time off work due to illness as well as injury, subject to the policy terms.

Will a year on parental leave reduce my KiwiSaver government contribution?

It can. The full government contribution of $260.72 requires you to contribute at least $1,042.86 of your own money between 1 July and 30 June, and employer contributions do not count toward that ⁴⁵. If your own contributions fall short during a reduced-income year, the top-up is scaled back to 25 cents per dollar of what you actually contribute. Some people make a voluntary lump sum before 30 June to reach the threshold, if their budget allows.

Is it better to sort life and income cover before the baby arrives?

Some steps are easier earlier. Most life and income cover is underwritten, and pregnancy can lead an insurer to defer or apply temporary terms, so reviewing cover before or early in a pregnancy can be more straightforward. Whether a claim is paid always depends on the policy terms, exclusions, stand-down periods, underwriting and your disclosure.
