How much should I save each month?

The commonly cited rule in NZ is 20% of after-tax income toward savings and debt repayment (the 50/30/20 split). But housing costs in Auckland and Wellington mean many Kiwis realistically save 10-15% — start where you can and automate the transfer on payday.

What's the fastest way to save money in NZ?

Do a subscription audit first — most Kiwis have $50-150/month in recurring charges they've forgotten about. Next, check your power and internet providers against Powerswitch; switching often saves $200-400/year. Then automate savings on payday so it doesn't depend on willpower.

Can Steady help me save automatically?

Steady shows you your safe-to-spend amount, tracks progress on savings goals, and sends alerts when you're close to overspending. Because NZ banks don't yet support automated bank-to-bank transfers through Akahu, actual money movement still happens in your bank app — but Steady tells you exactly when and how much.

Kia ora. Fuel is one of those costs that feels fixed but really isn't — the price swings weekly, and where and how you fill up makes a real difference. Here's what petrol costs in NZ in 2026 and how to spend less on it.

The short version

91 unleaded sits roughly $2.60–$3.10/litre in 2026, depending on region and world oil prices.
The average commuter spends $50–$90/week on fuel.
Fuel apps, discount dockets and fuel cards can shave 10–20c/litre — real money over a year.

What the average driver spends

Driving	Typical weekly fuel spend
Light (short commute, mostly local)	$30–$50
Average commuter	$50–$90
Heavy (long commute, big car)	$100+

Prices vary a lot by region — main centres are usually cheaper than remote areas. Always worth checking, not assuming.

Steady tip: Fuel is easy to underestimate because it's a few taps here and there. Steady groups your transport spending automatically so you see the real monthly number. Join the waitlist for early access.

How to cut your fuel bill

Use a fuel-price app (Gaspy and similar) to find the cheapest station nearby — the gap between stations can be 20c+/litre.
Stack discounts: supermarket fuel dockets, loyalty schemes (AA Smartfuel), and fuel cards add up.
Drive smoother: gentle acceleration, correct tyre pressure and less idling genuinely cut consumption.
Combine trips so you're not making multiple cold-engine short runs.

Fuel in your budget

Treat fuel like any other recurring cost — give it a weekly line and track it. If it's creeping up, it's usually more driving or a pricier station habit, both fixable. See building a household budget.

The bottom line

Petrol is ~$2.60–$3.10/litre in 2026 and the average commuter spends $50–$90/week. A fuel app plus stacked discounts is the easiest win; smoother driving and combined trips do the rest.

Steady tip: Steady tracks your fuel and transport spend so you can see whether that new commute or car is actually costing what you think. Join the waitlist.
