How much does a CT scan cost in NZ? Free routes and real prices

Who pays for your CT?

A CT has one more door than an MRI. The free-through-your-GP route does not yet exist for MRI; for a CT it does: a GP, urgent care doctor or nurse practitioner can order a CT directly, without a specialist or an emergency department first, and if the request meets the criteria it is free. Most money questions about CT are really questions about which of four doors the referral goes through, and who has to say yes at each.

Routes checked 13 September 2026; the ACC documents were last read 9 September 2026. For a CT patient the ACC row means this: if the clinic is billing your scan to ACC under the high-tech imaging service schedule that took effect on 1 July 2026, the only extra charge it may make is a reasonable fee for an out-of-hours slot you asked for and agreed to first — outside 8.30 am to 5 pm on a weekday.

Whether the clinic is billing ACC is the clinic’s knowledge, not yours, so ask. River Radiology marks every line of its CT list “ACC HIGHTEC: Fully Funded $0”; Allevia’s CT page says “ACC: No Charge – Specialist Referred only”, and those last three words are the catch. ACC’s high-tech imaging pathways are specialist-led and most procedures need written prior approval; the direct GP route ACC runs for selected knee and spine injuries is an MRI pathway, not a CT one. Outside the contract the ordinary rule applies: ACC helps pay for a covered injury, you may have to pay part, and you ask the provider how much. Our ACC imaging guide covers the claim itself.

Which CT scans are free through your GP?

The ones on the list. Health New Zealand publishes the National Community Referral Criteria for Imaging as one national document (version 2.0, 9 April 2026, linked from its radiology care pathways page), and it names, examination by examination, what a GP can order without a hospital specialist. For adults the CT sections are chest-abdomen-pelvis, chest, colonography, head, urogram and renal, KUB, sinus, and an “other” section that leans on a radiologist’s or specialist’s advice. Your GP sends the request, a primary care radiology liaison checks it against the criteria and gives it a priority, and if it is not accepted it goes back to your GP with the reason. Accepted means free.

The examples below are the criteria’s own words trimmed for a lay reader. They show the shape of the list, not a way to diagnose yourself; your GP still has to make the case.

Examples taken from the criteria document. The triage target is the wait-list priority the criteria attach to an accepted request, not a promise about your appointment. Delivery is arranged locally, and the national plan projected a fully implemented programme from July 2026.

Just as useful is what the same document says it does not routinely fund. CT cardiac, CT spine, CT biopsy, CT lower-limb angiography and CT joints are not yet on the list; they still need a referral to a hospital specialist, and the document says plainly that the patient may wish to consider privately funding the scan. The list has a logic, and this is my reading rather than anything the authors wrote down: the funded scans settle a question in general practice on their own — a stone, a sinus, a worrying headache, a suspected cancer with no site. The excluded ones are usually the second step in a decision a specialist is already making, so funding the scan without the specialist would buy a picture and not a plan. A PET-CT pairs CT with a radioactive tracer and has its own referral and funding rules; our PET scan guide covers them.

Two boundaries. The criteria do not cover imaging that ACC or another funding stream pays for, or screening, so an injury CT lives in the ACC row above. And the free scan is done wherever the local service arranges it, which may itself be a private clinic under contract; the private door is the one you open yourself. Our guide to who qualifies for free imaging covers the wider rules; the CT clinic list further down is where the private route starts.

What does a private CT cost?

Most clinics do not publish a price. On 13 September 2026 I checked eight New Zealand providers that offer CT, and two publish a list. Pacific Radiology, Bay Radiology and Auckland Radiology Group publish a pay-on-the-day policy with no figures. I-MED Radiology NZ gives prices by phone or email. Allevia asks you to send a copy of your referral for an estimate. Canopy Imaging’s CT page carries no price at all. The two exceptions are a Waikato practice and an Auckland one, and because they list the same examinations you can see how far apart two clinics can sit on the same request.

Figures from River Radiology’s pricing page and Auckland X-Ray Services’ transparent pricing page, both read 13 September 2026. River states that its prices are estimates only and may change without notice. These are two practices’ own lists, not a national rate, and a third clinic may quote you more or less for the very same referral.

Read the table for its shape, not for one number. Contrast is a separate line on a CT list; River’s MRI section on the same page has no contrast line at all. If your referral says “with contrast”, add that line; our guide to CT contrast explains what the injection is for.

The third region costs far less than the first. Adding the chest to an abdomen-and-pelvis scan costs $115.00 at River and $300.00 at Auckland X-Ray, because you are buying scanner time and one report, not three visits; the scanner couch slides through in a single pass.

And the scans the free list excludes are the hardest to compare. A spine study is listed at $1,075.50 in Hamilton and $675.00 in Auckland with different wording on each list, so I would not call them the same examination, and I would not book either without a second quote.

Can I get a CT without a referral?

No. You need a referral from your healthcare provider and you cannot self-refer, at a public hospital or a private clinic. I am on the side of that rule: a CT uses a small but real dose of radiation, and someone who knows your history should decide the picture is worth it. The most direct route is also the cheapest: a GP, urgent care doctor or nurse practitioner can write the referral, and if your problem is on the community list they can order the scan free. Once you hold a referral you may take it privately; the scan can be done in the public system or privately, and Auckland X-Ray Services says on its own site that patients may choose any imaging provider whatever the referral form. Our referral guide covers who can request which scan.

Find a clinic and ask for the number

Because most clinics do not publish a price, the practical move is to pick two you can get to and send each the same referral. Our CT clinic list groups New Zealand clinics whose own website names CT, by brand, region and city, with a map and each clinic’s address and phone number. Three of the clinics on it, each checked against the provider’s own page on 13 September 2026:

Three examples from a longer list, in no particular order and with no endorsement implied. Services and prices can change after our check, so the total for your own referral is the one thing to confirm by phone.

The other clinic in the price table needs a footnote. River Radiology at 30 Hood Street, Hamilton is in our directory, but the record does not yet list CT, so it is missing from the CT list above. The prices come from River’s pricing page, and its CT page names the Hood St and Te Rapa clinics that do the scans. Every directory, ours included, is a snapshot; the phone call makes it current.

If a public or community request is already in the system, find out where it has got to before you pay for anything. For a different scan, the MRI, ultrasound and X-ray cost guides do the same job.

Sources and review

Reviewed 13 September 2026 against Health NZ scans and x-rays, Health NZ CT scan, Health NZ community referred radiology, the National Community Referral Criteria for Imaging, version 2.0, and the published price, payment and service pages of River Radiology, Auckland X-Ray Services, Allevia Radiology, I-MED Radiology NZ, Pacific Radiology, Bay Radiology, Auckland Radiology Group and Canopy Imaging. The ACC rules follow the high-tech imaging service schedule, the operational guidelines and ACC’s treatment page, last read 9 September 2026. Prices are the clinics’ own published figures on the day they were read and can change without notice. Directory examples were checked against the live Radiology Clinics NZ listing and the provider’s current page on the same day. No clinic count, national price, waiting time or insurance rule is published here beyond what the named source states.

This article is general information, not personal medical advice. Ask your referrer which service is available, and ask the clinic whether public funding or ACC cover applies and what you will need to pay.
