If you have a KiwiSaver account, April 2026 brings a change that hits your pay packet directly. The minimum contribution rate rises from 3% to 3.5% for both employees and employers starting 1 April 2026, with a further increase to 4% planned for April 2028 (Inland Revenue (New Zealand’s tax and revenue authority)). The phased approach means most enrolled workers will see automatic deductions increase, though there is a temporary reduction mechanism for those who apply. Here is what the numbers actually mean for your take-home pay and retirement savings.

Is KiwiSaver going up to 4%?

Yes. The increase is being rolled out in two stages: 3% to 3.5% on 1 April 2026, then 3.5% to 4% on 1 April 2028 per Inland Revenue. The two-step approach was designed to give workers and employers time to adjust payroll systems and personal budgets.

Current rates

Before 1 April 2026, the default KiwiSaver contribution rate was 3% of before-tax pay. Both employees and employers paid this minimum. Employees could choose higher rates—4%, 6%, 8%, or 10%—but the default remained at 3% for those who did not actively select a different rate per Simplicity (low-fee KiwiSaver provider).

2026 increase to 3.5%

From 1 April 2026, the minimum rate rises to 3.5%. Employees contributing at the default 3% rate will see automatic increases to 3.5% with no action required from them per Inland Revenue. The increase applies to all paydays on or after that date, including pay periods that span before and after 1 April 2026. For someone earning $60,000 annually, the 0.5% increase translates to approximately $6 per week extra deducted from pay per Koura Wealth (NZ financial advisory).

The upshot

Workers on the default rate will see automatic deductions increase from 1 April 2026. Those already contributing above 3% will not have their rate changed, but their employer contributions will rise to meet the 3.5% minimum.

The implication: automatic enrollment means most default contributors will build retirement savings faster without lifting a finger, but the trade-off is a slightly thinner pay packet.

Future 4% hike

The default KiwiSaver contribution rate will rise again to 4% from 3.5% on 1 April 2028 per Booster (NZ KiwiSaver provider). This planned second increase was part of the Budget 2025 package designed to encourage Kiwis to save more for first homes and retirement per Inland Revenue.

Bottom line: The implication: workers who stay on the default rate will see two separate pay deductions increases within two years.

What is the minimum contribution to KiwiSaver?

The minimum contribution is currently 3% of before-tax pay, rising to 3.5% from 1 April 2026. Employees must contribute at least this amount to qualify for the Government contribution and receive employer matching per Simplicity.

Employee minimum

Employees are required to contribute a percentage of their before-tax pay to their KiwiSaver account. The compulsory rate is 3% rising to 3.5% in April 2026. Available contribution rate options include 3.5%, 4%, 6%, 8%, and 10% per Simplicity. Those wanting to contribute more can notify their employer using the KS2 form.

Employer matching

Employers generally must match employee KiwiSaver contributions at the same minimum rate per Simplicity. Some employees may be exempt from compulsory employer contributions, such as those under 18 or over 65, depending on when they joined the scheme and how long they have been in the fund per MYOB Enterprise Support (NZ payroll systems provider).

The catch: if an employee is already contributing more than 3%, their rate stays the same, but their employer must still increase their own contribution to at least 3.5% per Inland Revenue.

Why this matters

Workers earning above $30,000 at the default 3.5% rate will qualify for the full $260.72 Government contribution without needing to add extra. Those earning less or contributing less than the threshold may leave free Government money unclaimed.

What this means: workers earning above $30,000 can simply stay on the default 3.5% track and automatically receive the full Government match.

Government threshold

The Government contributes 25 cents for every $1 contributed, up to a maximum of $260.72 annually per Booster. This rate took effect on 1 July 2025. To receive the full Government contribution of $260.72 per year, employees must contribute at least $1,043 annually per Simplicity. Most employed Kiwis earning over roughly $30,000 per year and contributing the default 3.5% will automatically exceed this $1,043 annual threshold.

What are KiwiSaver changes in 2026?

Several changes took effect around the same time in early 2026. Inland Revenue announced the full package on 19 March 2026 per Inland Revenue, with the temporary rate reduction mechanism announced earlier on 20 January 2026 per Inland Revenue (official news update).

Contribution rate updates

From 1 April 2026, the minimum contribution rate increases from 3% to 3.5% for both employees and employers per Booster. The change was introduced in Budget 2025 to encourage Kiwis to save more for first homes and retirement per Inland Revenue.

Default adjustments

Employees contributing at the default rate will see automatic increases to 3.5% with no action required per Inland Revenue. However, employees can apply to Inland Revenue for a temporary rate reduction to remain at 3% between 3 and 12 months per Inland Revenue. Applications opened on 1 February 2026 via the myIR online portal per Inland Revenue.

What this means: the reduction does not take effect until an employee’s first payday on or after 1 April 2026, even if the application is approved before that date per Inland Revenue. Employees must show their employer a certificate confirming their KiwiSaver rate reduction if they apply for one.

Impact on savers

The phased increase gives workers a window to adjust. Workers who apply for the temporary reduction and are approved can stay at 3% for up to a year. Employees can apply for rate reductions multiple times after the initial 12-month period expires per Inland Revenue.

The trade-off: staying at 3% means missing out on the extra Government-matched savings during the reduction period, and employer contributions will also stay at the lower matching rate.

What is KiwiSaver employer contribution?

Employers must match employee contributions at the minimum rate. From 1 April 2026, this minimum rises to 3.5% per Booster.

Minimum employer rate

Employers generally must match employee KiwiSaver contributions at the same minimum rate per Simplicity. When an employee moves to a higher contribution rate, the employer must increase their contributions to match the compulsory 3.5% rate or higher per Inland Revenue.

Maximum tax credit

There is no specific maximum employer contribution. However, the Government contribution is calculated based on employee contributions only, up to the $260.72 annual cap per Simplicity. Higher employer contributions do not generate additional Government credits.

Matching rules

Employers can reduce their contribution to match an employee’s reduced rate once the reduced rate takes effect per Inland Revenue. Employers must end an employee’s temporary rate reduction if the employee provides a KS2 form to change their contribution rate to a higher level per Inland Revenue.

What to watch

Extending employer contributions to 16- and 17-year-olds is a notable expansion that brings more young workers into the KiwiSaver ecosystem, potentially accelerating their retirement savings from the start of their working lives.

The implication: extending employer contributions to 16- and 17-year-olds from 1 April 2026 means younger workers now receive the same matching benefit as older colleagues.

What is KiwiSaver government contribution?

The Government contributes to KiwiSaver accounts as an incentive for workers to save. This is not a payment from your employer but a direct payment from the New Zealand Government per Booster.

Eligibility minimum

To receive the full Government contribution, employees must contribute at least $1,043 annually per Simplicity. The Government contributes 25 cents for every $1 contributed, up to a maximum of $260.72 annually per Booster. Since 1 July 2025, this rate represents a change from the previous calculation per Booster.

Annual amount

The maximum Government contribution is $260.72 per year per Booster. 16- and 17-year-olds now qualify for Government contributions under the updated scheme per Booster.

Claim process

Contribute at least enough to receive the full Government contribution of $260.72 per year per Simplicity. The Government contribution is paid directly into the KiwiSaver account and does not require a separate claim application. It is calculated annually based on verified contributions.

Bottom line: KiwiSaver is raising its minimum from 3% to 3.5% on 1 April 2026, then to 4% in April 2028. Employees on the default rate will be auto-enrolled in the higher rate with no action required. Workers facing financial hardship can apply for a temporary 3–12 month reduction at 3% via myIR before 1 April 2026. Most workers earning over $30,000 will qualify for the full $260.72 Government contribution automatically.

What authorities are saying

The default KiwiSaver contribution rate will rise again to 4% from 3.5% on 1 April 2028.

— Inland Revenue

From 1 April 2026, the minimum KiwiSaver contribution rate for employees and employers will increase from 3% to 3.5%.

— Booster

Contribute at least enough to receive the full Government contribution of $260.72 per year.

— Simplicity

The phased KiwiSaver contribution increases represent the most significant adjustment to New Zealand’s retirement savings minimums in recent years. With the 3.5% rate taking effect on 1 April 2026 and the 4% rate confirmed for April 2028, workers have a narrow window to decide whether to stay on the default track or apply for a temporary reduction. The Government contribution remains a compelling reason to at least meet the $1,043 annual threshold that unlocks the full $260.72 credit.

Frequently asked questions

How much should you have in KiwiSaver at 40?

There is no mandatory target, but general guidance suggests having roughly three to four times your annual salary saved by age 40. The increase to 3.5% (and eventually 4%) from the previous 3% minimum means workers will accumulate more automatically over time.

What is the 4% rule on KiwiSaver?

The 4% rule refers to the planned future minimum contribution rate scheduled to take effect on 1 April 2028. Currently, the minimum is 3% rising to 3.5% on 1 April 2026. The 4% rate will apply to both employee and employer contributions.

Is NZ Super going up in 2026?

NZ Superannuation rates are set independently by the Government and are not directly tied to KiwiSaver contribution rate changes. Higher KiwiSaver balances may eventually reduce reliance on NZ Super, but NZ Super rates are determined through separate review processes.

What happens to KiwiSaver if I move overseas?

KiwiSaver accounts remain open even if you leave New Zealand, though contribution requirements change. You can withdraw your savings (except for the Government contribution) after certain conditions are met. Contact your KiwiSaver provider for specific rules on overseas residency and withdrawals.

How many people have $1,000,000 in retirement savings?

While specific New Zealand statistics vary, the number of KiwiSaver members with balances approaching $1,000,000 is growing as the scheme matures and contribution rates increase. Higher minimum rates from 3.5% to 4% should accelerate balance growth over time.

How do I change my KiwiSaver contribution form?

Employees use the KS2 form to change their KiwiSaver contribution rate. You can submit this to your employer to increase your rate above the minimum or to end a temporary rate reduction. Employers must act on KS2 form submissions promptly per Inland Revenue.

What is the maximum employer KiwiSaver contribution?

There is no set maximum for employer KiwiSaver contributions. However, only employee contributions up to the $1,043 annual threshold qualify for the full Government $260.72 contribution. Employers who match at higher rates still only receive Government credits based on employee contribution levels.

When does the 4% minimum take effect?

The 4% minimum contribution rate is scheduled to take effect on 1 April 2028 per Booster. This represents the second stage of the two-step increase from the previous 3% rate.

For workers wondering whether to apply for the temporary rate reduction before 1 April 2026, the math is relatively straightforward: those who stay at 3% will save roughly $6 per week on a $60,000 salary, but they will also miss out on the extra Government-matched savings and may face a larger adjustment when the 4% rate arrives in 2028.

For New Zealand employees, the choice is clear: apply for a temporary reduction now if cash flow is tight, or accept the automatic 3.5% increase now and build more retirement savings sooner. Those choosing the reduction can always reapply after 12 months if needed.
