Knee replacement cost in New Zealand
What goes into a private knee-replacement quote — and how to find out what your specific cover pays.
The four parts of a private knee-replacement quote
- Hospital / theatre fees. Operating-theatre time, ward bed-nights (typically a few nights post-op), recovery, consumables. Each private hospital publishes its own day-rate. The hospital itself is the entity you ask for an estimate. Use Source: HealthPoint ↗ to find the private hospitals near you.
- Orthopaedic surgeon's fee. Quoted by the surgeon directly. Two surgeons at the same hospital can quote different fees for the same operation. A first consult with the surgeon will produce a written fee proposal.
- Anaesthetist's fee. A separate practitioner, quoting separately. Their fee depends on the complexity and length of the surgery.
- Implant / prosthesis. Knee prostheses vary by manufacturer, material and design (e.g., partial vs total replacement). The implant is itemised on the hospital bill.
Public vs private pathway
New Zealand's public system funds joint replacements but allocates them by clinical priority, with planned-care wait times published by Health NZ. People who don't meet the clinical threshold, or who can't wait, use private cover to access the operation on their preferred timeline.

What private health insurance actually pays
Most major NZ private health policies cover elective joint replacement under hospital cover, subject to:
- Joint-replacement sublimit — a maximum the policy pays per joint, set out in the wording.
- Excess — the amount you pay before the policy contributes (if you've chosen an excess option to lower your premium).
- Pre-existing-condition rules — knee issues you had before taking out the policy may be excluded permanently or for a stand-down period.
- Surgeon and anaesthetist sublimits — some policies cap the specialist fees separately from the hospital fees.
Each insurer's wording PDF spells these out verbatim. We pull the extracted facts from current wordings on our compare providers page so you can see Southern Cross, nib, AIA, Accuro and UniMed side by side.
Practical steps to a real number
- Get a GP referral to two private orthopaedic surgeons. Most insurers don't require this for the quote stage.
- Each surgeon writes a quote covering their fee + the proposed hospital + estimated implant + anaesthetist contact.
- Ring the hospital and ask for a written all-in estimate.
- Send the estimates to your insurer for pre-approval — they'll tell you what the policy pays vs what you'd pay out of pocket.
- If you don't yet have cover, get quotes from multiple insurers and check the joint-replacement sublimit before you sign up.
