$10,000 extra hits firms running a $2 million payroll from April

A business with ten employees on average salaries of $70,000 is now paying $3,500 more per year in KiwiSaver contributions. That figure doubles to $7,000 when the second increase to 4% kicks in on 1 April 2028. A firm running a $2 million payroll absorbs $10,000 in extra employer contributions from this change alone.

The increase, which took effect on 1 April, is the first movement in the default rate since it was set at 3% in 2013. Over a decade of stability, then a mandated jump that no employer had any say in. As Insight CA put it, the cost “hides in plain sight”, quietly inflating the labour line from the first pay run in April.

Three cost increases hit the same week

KiwiSaver is not arriving alone. From the same date, employers are also absorbing a minimum wage increase to $23.95 per hour, affecting 122,500 workers on the lowest legal rate, and a 4.5% rise in the ACC Work Levy to $0.69 per $100 of liable earnings.

No single increase is catastrophic. Together they represent a meaningful squeeze on operating margins, particularly in labour-heavy sectors like hospitality, retail, trades, and care.

Ashlea Maley, Associate Director of Operations at Peninsula New Zealand, is blunt about the pressure: “The current economic climate is placing significant pressure on small businesses, with many facing rising payroll obligations at a time when operating conditions are already tough.”

The total remuneration trap catches employers both ways

Businesses that structure pay on a total remuneration basis face a specific sting. Under this model, the salary package is defined as inclusive of employer KiwiSaver contributions. When the rate rises, the employer must fund the combined increase from within the existing package, effectively absorbing both the employer and employee share. The employee’s take-home pay drops more sharply, and renegotiating existing contracts mid-cycle is rarely simple.

RSM notes that businesses can use total remuneration to manage future cost increases, but for contracts already locked in, the April change creates an immediate double-hit.

Separately, employers must now make KiwiSaver contributions for eligible employees aged 16 and 17 who are KiwiSaver members. This is an entirely new obligation. For businesses running large casual youth workforces, it is a cost line that did not exist before April.

The long-run argument is right but useless right now

Westpac chief economist Kelly Eckhold makes the standard incidence case: “Changing the allocation of what employees do with that remuneration is not likely to change that assessment” of total compensation. Treasury analysis supports this, suggesting increased employer costs could be absorbed through lower-than-otherwise wage growth over time.

Theoretically coherent. Practically useless for the SME writing a larger payroll cheque in April before any wage negotiation cycle plays out. The long-run incidence argument assumes flexible wage adjustment, not a world of employment agreements, minimum wage floors, and inflation back above 3%.

The government pulled back its own contribution while expanding yours

The retirement savings case is genuine. Te Ara Ahunga Ora Retirement Commission projects that a 35-year-old earning $80,000 could see approximately 25% more savings at age 65 by moving from 3% to 4%. Nobody seriously argues that New Zealanders are saving enough.

But it is worth naming the government’s own trade-off. Budget 2025 simultaneously halved the maximum government contribution from $521.43 to $260.72 per year while mandating that employers and employees contribute more. The government is retreating from its own financial commitment to the scheme while expanding compulsory obligations on private parties.

This is not over

NZIER’s latest survey shows business confidence at its highest since 2014, but firms continue reporting weak domestic demand and subdued profitability. Sentiment has run ahead of revenue. Adding mandated payroll costs into that gap does not improve hiring intentions.

The second increase to 4% arrives in April 2028. Any business that has not modelled the full two-stage impact on its payroll is already behind. The cost does not arrive as a sudden invoice. It just quietly erodes your margin, pay run by pay run, until someone finally checks the numbers.
