KiwiSaver Changes from 2026: What Employers and Employees Need to Know

Gina Gambitsis • January 22, 2026

First changes due in February to time to prepare

From 2026, KiwiSaver will undergo some of the most significant changes in recent years. These reforms will affect both employers and employees, with higher contribution rates, expanded employer obligations, and new flexibility options.

Whether you run a business or are part of the workforce, now is the time to understand what’s changing—and what you need to do to prepare.

Why KiwiSaver Is Changing

KiwiSaver is governed by the KiwiSaver Act 2006, which aims to help New Zealanders build long-term savings for retirement and, in some cases, a first home.

Following Government policy changes announced in Budget 2025, KiwiSaver contribution rates will increase in stages from 2026. The goal is simple: improve retirement outcomes for New Zealanders by gradually lifting savings levels over time.

The Key Changes from 2026

1) Higher KiwiSaver Contribution Rates

From 1 April 2026, the default minimum KiwiSaver contribution rate will increase:

  • Employee contributions: from 3% to 3.5%
  • Employer contributions: from 3% to 3.5%

This is the first stage of a planned increase, with the default rate rising further to 4% from 1 April 2028.

For employees, this means slightly higher deductions from pay.
For employers, it means increased payroll costs and the need to update systems and budgets.

2) Employer Contributions for 16–17 Year Olds

Currently, compulsory employer KiwiSaver contributions generally apply to employees aged 18 to 65.

From 1 April 2026, employers will also be required to make KiwiSaver contributions for eligible 16 and 17 year old employees who are KiwiSaver members.

This is an important change for businesses employing younger staff, particularly in retail, hospitality, and part-time roles.

3) Temporary Contribution Rate Reductions

Recognising that higher contribution rates may not suit everyone, employees will be able to apply for a temporary reduction in their KiwiSaver contribution rate.

  • Applications open from: 1 February 2026
  • Reductions take effect from: 1 April 2026
  • Reduced rate: back to 3%
  • Inland Revenue will notify employers of approved reductions.
  • Employers may choose whether to match the reduced rate.

This flexibility allows employees to manage cash flow while still remaining in KiwiSaver.

KiwiSaver Change Timeline

1 February 2026

  • Employees can apply to Inland Revenue for temporary rate reductions.

1 April 2026

  • Default employee and employer contribution rates increase to 3.5%.
  • Employer contributions become compulsory for eligible 16–17 year olds.
  • Temporary rate reductions take effect.

1 April 2028

  • Default contribution rates increase further to 4%.

Tax and Payroll Implications for Employers

From a tax perspective:

  • Employer KiwiSaver contributions remain tax-deductible business expenses.
  • However, increased contribution rates will raise overall payroll costs.

From a compliance perspective:

  • Payroll systems must be updated to reflect new rates from 1 April 2026.
  • Employers must action notifications from Inland Revenue regarding employee rate changes.
  • Employment contracts, payroll policies, and internal processes may need review.

Failing to apply the correct rates could result in compliance issues with Inland Revenue.

Why This Matters

For employees, the changes mean stronger long-term retirement savings, albeit with a small impact on take-home pay.

For employers, the reforms highlight the importance of:

  • forward planning,
  • budgeting for increased payroll costs, and
  • ensuring payroll systems and processes are ready well before April 2026.

What Should Businesses Do Now?

To prepare for the changes, employers should:

  • Review payroll systems and software.
  • Update internal payroll and HR procedures.
  • Communicate upcoming changes to staff.
  • Budget for higher employer contributions.
  • Identify employees aged 16–17 who may become eligible.

Early preparation will make the transition smoother and reduce compliance risk.

Navigating the ins and outs of business expenses and tax deductions can feel overwhelming for many New Zealand business owners. However, understanding what expenses you can claim can significantly reduce your taxable income, ensuring you don’t pay more tax than necessary. Fortunately, the New Zealand tax system is clear about which business expenses are deductible, and with the help of professionals like GCOL Chartered Accountants, you can make sure you’re maximizing your claims. What Are Business Expenses in New Zealand? In simple terms, business expenses are the costs incurred in the day-to-day running of your business. These expenses are essential to generating your business income and are therefore deductible, meaning you can subtract them from your revenue to determine your taxable income. The New Zealand Inland Revenue (IR) Department has guidelines to help business owners understand what expenses are claimable. Here's a breakdown of the most common claimable business expenses: 1. Operating Expenses These are the costs involved in keeping your business running. Examples include: Rent and Utilities : The cost of renting office space or premises, as well as utilities like electricity and water, are claimable. Insurance : Premiums for business insurance (e.g., property, liability, and vehicle insurance) are deductible. Advertising and Marketing : Costs associated with promoting your business, such as online ads, print advertising, and marketing campaigns, can be claimed. Office Supplies : Items such as paper, pens, computers, and other office-related expenses are eligible for deduction. Bank Fees and Interest : Fees for business accounts and interest on business loans are deductible. 2. Vehicle and Travel Expenses If you use your vehicle for business purposes, you can claim a portion of the vehicle expenses, which may include: Fuel, Repairs, and Maintenance : If your vehicle is used for business, you can claim the costs proportionate to business use. Travel Expenses : Airfares, accommodation, and meals while traveling for business purposes are deductible. Remember, personal use of the vehicle or travel expenses cannot be claimed. You will need to apportion these costs based on business use. 3. Employee and Contractor Costs If you have employees or contractors, the following are claimable expenses: Salaries and Wages : Payments to employees, including bonuses, holiday pay, and KiwiSaver contributions, are deductible. Contractor Fees : If you hire independent contractors, their fees are also claimable. Training and Development : Costs associated with training and developing your team are deductible, so long as they are relevant to your business. 4. Depreciation Some business assets, such as equipment, vehicles, or buildings, lose value over time. Instead of claiming the full cost in one go, you can claim depreciation on these assets. The IRD provides depreciation rates for various asset types. 5. Professional Services If you hire professionals to assist with your business, their fees are claimable, including: Accountant and Legal Fees : Fees for financial advice, tax preparation, or legal assistance related to business activities can be deducted. Consulting Fees : If you engage business consultants for services such as market research or business planning, these expenses are also claimable. 6. Home Office Expenses Many small business owners or sole traders work from home. If this applies to you, you can claim a portion of your home-related expenses, such as: Mortgage Interest or Rent : If you work from home, you can claim a percentage of your mortgage interest or rent based on the portion of your home used for business. Electricity and Internet : You can also claim a portion of your electricity, phone, and internet costs based on the percentage of time you use them for business.
