When you join KiwiSaver for the first time, the default contribution rate is 3.5% for both employees and employers, with payments made automatically each time you're paid your salary/wages.

You can choose to contribute more - 4%, 6%, 8% or 10% - by notifying your employer or updating your rate through MyIR.

Matching employer contributions of 3.5% are mandatory for employees aged 16 to 65. Some employers may contribute more or continue contributions beyond that age range.

Recent policy changes mean the default contribution rates are gradually increasing. They rose from 3% to 3.5% on 1 April 2026, and will increase again to 4% from 1 April 2028.
