KiwiSaver Explained Simply

A visual, story-based guide to understanding how KiwiSaver actually works. With real numbers and examples.

Let's Follow the Money: Sarah's Story

S

Sarah, Age 28

Earns $70,000/year at a marketing agency in Wellington

Sarah joined KiwiSaver when she started her job. Let's see exactly where her money goes and how it grows over time.

1

Payday: Money Leaves Her Account

Sarah's Gross Pay (Fortnightly)
$2,692
$70,000 ÷ 26 pay periods
Sarah's KiwiSaver Contribution (3%)
-$81
Automatically deducted
Sarah's Take-Home Pay$2,611
(after KiwiSaver, before tax)

💡 Key Point: Sarah contributes 3% (the minimum). She could choose 4%, 6%, 8%, or 10% if she wants to save more. Her $81 comes out before tax, which means she gets a small tax benefit.

2

Employer Adds Free Money

Employer Adds (3% match)
+$81
Total Going Into KiwiSaver$162
Every fortnight

💰 Free Money: Sarah's employer must match her contributions up to 3% of her salary. This is compulsory by law - every employee gets this.

Annual total: $162 × 26 pay periods = $4,212/year($2,106 from Sarah + $2,106 from employer)

Government Adds Even More Free Money

Sarah's Annual Contribution
$2,106
Government Contribution (50% match, max $521)
+$521
Deposited once a year (July 1st)
Sarah's Total Annual KiwiSaver$4,733

🎁 How it works: The government adds 50 cents for every dollar you contribute, up to $521 per year. To get the full $521, you need to contribute at least $1,042/year.

Sarah contributes $2,106/year, so she gets the full $521. This is free money for saving for retirement!
