The first year with a baby is one of the most financially significant periods in many New Zealanders’ lives — and one of the least well-prepared for. Between lost income from parental leave, new baby gear, healthcare, and eventual childcare costs, it’s common for first-time parents to spend $15,000–$30,000 more than usual in the 12 months following birth.
The direct costs of a baby in the first year in NZ are $8,000–$18,000 — including gear, healthcare, nappies, formula (if applicable), and clothes. Adding the income loss from parental leave (if not on Paid Parental Leave) the total financial impact is often $20,000–$40,000 in year one. Best Start payments ($73/week for the first year) and Paid Parental Leave (up to $754/week) partially offset this.
One-Off Baby Setup Costs
These are the items you buy once — most can be bought second-hand at significant savings.
| Item | New price | Second-hand price |
|---|---|---|
| Cot / bassinet | $200 – $600 | $50 – $150 |
| Pram / stroller | $300 – $1,800 | $80 – $400 |
| Car seat (infant) | $200 – $600 | $0 (never buy second-hand — safety) |
| Change table | $100 – $350 | $20 – $100 |
| Baby monitor | $60 – $300 | $20 – $80 |
| Baby bath | $30 – $80 | $10 – $25 |
| Feeding equipment (bottles, steriliser) | $60 – $200 | $20 – $60 |
| Baby carrier / wrap | $50 – $250 | $20 – $80 |
| Swing / bouncer | $50 – $300 | $15 – $80 |
| Baby clothes (0–3 months) | $200 – $400 | $30 – $100 |
| Total (buying new) | $1,250 – $4,980 | |
| Total (second-hand, ex car seat) | $300 – $1,175 |
Never buy a second-hand car seat — you can’t verify its crash history. Everything else is fine second-hand.
Ongoing Monthly Costs — Year One
| Category | Monthly (breastfed) | Monthly (formula-fed) |
|---|---|---|
| Nappies (disposable) | $80 – $130 | $80 – $130 |
| Baby formula | — | $200 – $400 |
| Baby wipes | $20 – $35 | $20 – $35 |
| Clothing (growing fast) | $50 – $120 | $50 – $120 |
| Baby skincare / toiletries | $20 – $40 | $20 – $40 |
| Baby food (from 6 months) | $0 – $80 | $0 – $80 |
| Toys and books | $20 – $60 | $20 – $60 |
| Total ongoing monthly | $190 – $465 | $390 – $865 |
Formula costs are the most significant differentiator — standard NZ infant formula costs $20–$30/tin and a newborn goes through 1–2 tins/week. Breastfeeding eliminates this cost entirely (though there may be costs for lactation support if needed).
Healthcare — What Costs Money in Year One
Most baby healthcare in NZ is free or subsidised. Key costs to know:
| Service | Cost |
|---|---|
| Well child / Plunket visits | Free |
| Core vaccinations (scheduled) | Free |
| GP visit — under 14 years | Free (under 14s are fully subsidised) |
| Prescriptions — under 14 years | Free |
| After-hours / urgent care (under 14) | Free |
| Dental from age 0 (through school dental services) | Free until age 18 |
| Private paediatrician (if needed) | $250 – $450 per visit |
| Specialist referrals via public system | Free (may wait) |
Good news: Most routine baby healthcare in NZ is free. The main cost is private specialist care if needed — and most families never need it.
Parental Leave — Income During Year One
Paid Parental Leave (PPL)
Primary carer PPL (available to employed or self-employed people who have worked for 6 of the past 12 months):
| Week | PPL weekly rate (2026) |
|---|---|
| Weeks 1–26 | Up to $754/week (gross) |
| Weeks 27–52 | Extended leave at up to $178/week (if partner shares) |
Minimum payment: For those earning under $754/week, PPL replaces actual income (minimum is linked to minimum wage).
Partner/secondary carer: Up to 4 weeks of PPL can be transferred to the non-primary carer. Partners can also take up to 1 week of paid partner/paternity leave.
Best Start Payments
A universal payment for newborns for the first 12 months:
- All families: $73/week for the first year
- Lower income families: Continues from 12 months to age 3 (income-tested)
Best Start is paid by IRD automatically once you apply — apply via myIR when your baby is born.
The Income Drop — A Common Shock
Many families underestimate how significant the income drop is when one parent takes parental leave, especially if:
- They are self-employed (PPL exists but payment calculation is different)
- Their income is above the PPL cap ($754/week — equivalent to ~$78,000/year)
- The employer tops up PPL — some do, many don’t
Example — high earner on parental leave:
| Item | Weekly |
|---|---|
| Normal salary | $1,800 gross (~$1,400 net) |
| PPL rate (capped) | $754 gross (~$620 net) |
| Income loss | ~$780/week |
For high-earning parents, the income loss from PPL can be $3,000–$4,000/month. Build this into your financial planning before the baby arrives.
Childcare — The Biggest Cost After 6–12 Months
Many parents return to work at 6–12 months, when childcare becomes the dominant baby-related expense. Full-time daycare for under-2s in NZ costs $400–$620/week (before subsidies).

Tips to Keep Baby Costs Down
- Buy second-hand gear: Facebook Marketplace, Trade Me, and local parent groups have almost everything at 20–40% of retail
- Accept hand-me-downs: Babies grow so fast — clothing from 0–6 months is often barely worn
- Breastfeed if possible: Formula costs $2,400–$5,000 over 12 months
- Use cloth nappies: Upfront cost of $400–$800 but saves $1,500–$2,500 over 2 years vs disposables
- Borrow or rent big items: Prams, swings, and bouncers can be borrowed from friends
- Apply for Best Start immediately: $73/week from birth — apply via myIR as soon as you have a baby’s IRD number
- Check Childcare Subsidy eligibility: Apply well in advance of returning to work
