Why it comes first
Without savings, a $1,500 car repair goes on a credit card. At a typical 20.95%, paying it off at $100 a month takes 18 months and costs about $255 in interest. One surprise can turn into months of debt. An emergency fund breaks that cycle.
It also gives you breathing space if your income stops:
- Sick leave runs out after 10 days a year once you’ve been in a job for six months.
- ACC covers injuries, but not illness. See insurance basics.
- Redundancy pay isn’t required by law in New Zealand. You only get it if your employment agreement includes it.
How much do you need?
Add up your essential monthly costs only: rent or mortgage, groceries, power, transport, insurance and minimum debt payments. If you pay rent weekly, multiply it by 52 and divide by 12 to get a monthly figure. Then multiply:
| Your situation | Aim for |
|---|---|
| Steady job, no dependants | 3 months |
| Family, single income or a less secure job | 6 months |
| Self-employed or income that varies | 6 to 12 months |
Example: essentials of $3,000 a month mean a fund of $9,000 to $18,000.
Think about the big costs that tend to arrive without warning in New Zealand: car repairs before a warrant of fitness, dental work (adult dental care isn’t free), vet bills, and the excess on an insurance claim after a storm.
Where to keep it
- An on-call savings account, so you can get at it the same day. Many banks have one with no fees.
- A notice saver for part of it, if you can wait a few weeks for that money. It usually pays more.
- Separate from your everyday account, so it doesn’t get spent by accident. A different bank makes it harder to dip into.
- With a licensed bank, building society or credit union. The Depositor Compensation Scheme protects up to $100,000 per depositor at each one.
- Not in KiwiSaver or shares. KiwiSaver is locked away except for a first home, serious illness or significant hardship, and markets can fall just when you need the money.
Your bank takes resident withholding tax from the interest. Check it’s using the right rate for your income. If you’re on 30% or more, a PIE savings account can mean less tax.
How to build it from nothing
- Start with a small goal, such as $1,000 or one month of essentials.
- Set up an automatic payment on payday, even $25 or $50 a week.
- Add windfalls: part of a tax refund, bonus or pay rise.
- Once you have a starter fund, clear expensive debt, then build the rest.
- Saving $50 a week $1,000 in 20 weeks · $9,000 in 3 years 6 months
- Saving $100 a week $1,000 in 10 weeks · $9,000 in 1 year 9 months
- Saving $200 a week $1,000 in 5 weeks · $9,000 in 45 weeks
Before interest. Adding tax refunds, bonuses or a pay rise gets you there sooner.
When to use it
Use it for real emergencies: losing your job, urgent repairs, medical or dental bills. Not for holidays or Christmas: save for those separately. When you use it, top it back up before going back to other goals.
