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 (up to $77/week) and paid parental leave (up to $811.05/week before tax) 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 paid parental leave (for employees or self-employed people who have worked an average of 10+ hours a week for any 26 of the 52 weeks before the due date):
| Week | Paid parental leave (from 1 July 2026) |
|---|---|
| Weeks 1 to 26 | Your usual income, up to $811.05 a week before tax |
| After that | Extended leave from work is unpaid |
If you earn less than the maximum, the payment replaces your usual weekly income. Self-employed people get at least $239.50 a week.
Partner: the primary carer can transfer some or all of the paid parental leave to their partner (who must stop work and meet the work record). Partner’s leave from work (1 or 2 weeks) is unpaid.
Best Start Payments
Best Start pays up to $77 a week for each child under 3:
- Born on or after 1 April 2026: reduces above $79,000 family income from birth
- Born before 1 April 2026: first year paid in full; years 2 and 3 reduce above $79,000
- It starts after paid parental leave finishes (they can’t be paid at the same time for the same child)
Apply in 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 paid parental leave maximum ($811.05 a week, about $42,175 a year)
- The employer tops up PPL — some do, many don’t
Example — high earner on parental leave:
| Item | Weekly |
|---|---|
| Normal salary | $1,800 gross (~$1,369 net) |
| Paid parental leave (maximum) | $811.05 gross (~$676 net) |
| Income loss | the difference between the two net amounts |
For this parent that’s roughly $700 a week, or about $3,000 a month, and more for higher earners. 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).

Year One Budget Summary
| Category | Lower estimate | Higher estimate |

| One-off gear (mostly second-hand) | $600 | $5,000 |
| Ongoing monthly costs × 12 | $2,280 | $10,380 |
| Healthcare | $0 | $500 |
| Total direct baby costs | $2,880 | $15,880 |

| Total financial impact | $2,880 | $33,880 |
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 early: up to $77/week per child under 3; apply in myIR, ideally before paid parental leave ends
- Check Childcare Subsidy eligibility: Apply well in advance of returning to work
