Using KiwiSaver for Dental Implants, Inland Revenue Hardship Guide (2026)

What Is KiwiSaver Hardship Withdrawal?

KiwiSaver hardship withdrawal is a provision under the KiwiSaver Act 2006, administered by Inland Revenue (Te Tari Taake), that allows members to withdraw funds before retirement age in defined circumstances. For dental treatment, the relevant ground is significant financial hardship, specifically where the withdrawal is needed to meet necessary medical treatment expenses for you or your dependants.

This is not a standard withdrawal. The bar is high. IRD applies a test of necessity, not preference, and considers your total financial position, including income, savings, equity, and other funding options, before approving.

The Four Criteria IRD Applies

1. Medical necessity, the treatment must be necessary for your health, not purely cosmetic or elective

2. Inability to meet the expense otherwise, you must demonstrate that you cannot reasonably fund the treatment from income, other savings, loans, or insurance

3. Significant financial hardship, the cost must create genuine hardship relative to your financial position

4. KiwiSaver balance availability, your balance must exceed the minimum contribution balance; you may only withdraw above that threshold

Full-mouth implant cases that are functionally necessary (severe bone loss, inability to eat, significant health impact) are more likely to meet the necessity test than purely cosmetic cases. Borderline or purely aesthetic cases are unlikely to qualify.

How to Apply

Step 1: Obtain a supporting letter from your NZ registered dentist or specialist confirming the medical necessity of the treatment and the clinical scope required.

Step 2: Obtain a written quote for the treatment cost (SD provides written quotes in NZD for NZ Inland Revenue submissions).

Step 3: Complete the KiwiSaver hardship withdrawal application via myIR (Inland Revenue's online portal) or by paper form (KS-5 form).

Step 4: Provide supporting documentation: medical/dental necessity letter, treatment quote, evidence of inability to fund from other sources (bank statements, loan application results).

Step 5: IRD reviews and determines. Approximately 10–15 working days. Determination is in writing.

Step 6: If approved, funds are released from your KiwiSaver provider to your bank account. Not paid directly to the treatment provider.

Realistic Expectations

IRD approval rates for dental hardship applications are not publicly published. Anecdotally, applications with strong medical necessity documentation and clear financial hardship evidence succeed at higher rates than applications that are poorly documented.

A written clinical letter from a DCNZ-registered dentist (or SD's clinical team where we can provide supporting documentation for NZ applications) significantly strengthens an application.

What to do if rejected: Inland Revenue has a formal review process. You can request reconsideration and provide additional documentation. If the review upholds the rejection, the decision is final, KiwiSaver funds are not accessible via any other route before age 65 except under the other specified hardship grounds (mortgage default, terminal illness, etc.).

KiwiSaver Withdrawal vs Other Financing Options

KiwiSaver withdrawal appears "free" but carries an opportunity cost, the withdrawn amount loses future compounding in your retirement account. For patients approaching retirement, this cost is real and should be factored in with a financial adviser before applying.
