KiwiSaver Forms Explained (2026): Complete Guide for Employees & Employers
Last Updated: July 2026
Understanding KiwiSaver Forms is essential for both employees and employers in New Zealand. Whether you’re starting a new job, joining KiwiSaver, changing contribution rates, or managing payroll, completing the correct form helps ensure compliance with Inland Revenue (IRD) requirements. This guide explains the most commonly used KiwiSaver forms—including KS2, KS3, and KS10—along with employer responsibilities, payroll obligations, and common mistakes to avoid.
KiwiSaver is one of New Zealand’s most important long-term savings schemes, helping millions of New Zealanders save for retirement while also supporting eligible first-home buyers.
When employees begin a new job or wish to change their KiwiSaver contributions, both employees and employers are required to complete certain Inland Revenue forms. Choosing the correct KiwiSaver Forms helps ensure contributions are processed correctly, payroll records remain accurate, and employers meet their legal obligations.
Many people become confused by forms such as KS2, KS3, and KS10. Each serves a different purpose, and using the wrong form can delay enrolment or result in payroll errors.
This comprehensive guide explains each KiwiSaver form, when it should be used, employer responsibilities, payroll requirements, and practical examples to help employees and businesses stay compliant with Inland Revenue rules.
Quick Answer
What are KiwiSaver Forms?

What Is KiwiSaver?
KiwiSaver is a voluntary retirement savings scheme introduced by the New Zealand Government to help individuals build long-term savings.
Employees usually contribute a percentage of their salary or wages through payroll deductions, while employers are generally required to make compulsory employer contributions for eligible employees.
KiwiSaver savings can be used for retirement and, in certain circumstances, to help purchase a first home or in cases of significant financial hardship.
What Are KiwiSaver Forms?
KiwiSaver Forms are official documents issued by Inland Revenue that help employees and employers manage KiwiSaver enrolment, contribution rates, exemptions, and payroll administration.
Different forms are required depending on whether you’re:
- Starting a new job

- Applying for a savings suspension
- Managing payroll
- Updating employee information
Using the correct form ensures KiwiSaver contributions are processed accurately and in accordance with Inland Revenue requirements.
Why Are KiwiSaver Forms Important?
