DEXA Body Composition Scan NZ: Cost, Referral, Where to Go

What does the scan measure, and what doesn’t it?

Bathroom scales tell you what you weigh. They cannot tell you what that weight is made of, which is why the scale can sit still for a month while your jeans get looser.

DEXA (dual-energy x-ray absorptiometry) is the same technology used to check bone density. A thin, invisible beam of low-dose x-rays passes through your body. For body composition, the machine scans you from head to toe. The software then splits you into bone, lean tissue and fat, for your arms, legs, trunk and whole body. Four of the seven providers in our table below also estimate visceral fat, the fat packed around your organs: Bone and Body Blueprint, Canopy Imaging, Auckland Bone Density and Sharp Medical Imaging.

This is a measurement, not a diagnosis, and it is not an osteoporosis check. A bone density test for osteoporosis looks closely at your lower spine and both hips, and a radiologist reports it to the doctor who asked for it. Your body composition printout may show a whole-body bone figure, but that is not the spine-and-hip test a doctor uses to diagnose osteoporosis. At Bone and Body Blueprint, for example, you take the body composition report home on the day, while bone density results go to your GP within 5 to 10 working days. If your real question is about your bones, read our bone density scan guide first.

Is it safe, and who should skip it?

Yes, it is very safe. A DEXA scan uses a much lower level of radiation than a standard x-ray. There is no tunnel, no injection, and it does not hurt. The table is open, and the technologist stays in the room with you, which tells you how small the dose is.

Small is not zero, though. If you are booking it out of curiosity or for training, nothing is lost by waiting, so take the few exceptions seriously.

Where can you get one, and what does it cost?

Four of the seven providers below say you can book without a referral: Bone and Body Blueprint, Allevia, Canopy (if you are over 20) and Absolute Radiology. In the public system a DEXA scan needs a referral, but privately you can self-refer (our referral guide explains the difference). Referral rules still vary by clinic, as the table shows.

These are examples from our directory whose own pages confirmed a DEXA body composition service on 30 September 2026. It is not a complete list or a ranking. The prices are each clinic’s published private fee on that date.

Bone and Body Blueprint’s prices include GST. Form Imaging’s prices come from its Healthpoint pages for both branches, last updated 16 September 2026. Two more notes. Allevia lists this service at one location only, Ōrewa, so don’t book it at another branch by mistake. And in Hawke’s Bay, Canopy’s Sports Park clinic closes after 1 October 2026, and its DEXA service moves to Kaweka Hospital from 12 October.

For other towns, start at our bone density clinics page, which groups DEXA clinics by region. Not every clinic there offers body composition, so ask that question first.

How do you make the second scan worth paying for?

One scan gives you a snapshot. The useful part is the change between two scans, and the clinics know it. Form Imaging suggests one scan at the start of a new exercise plan and another every six months, and keeps your scans so it can compare them later. Bone and Body Blueprint prices a cheaper follow-up if you book it within six months.

Here is the catch. Canopy’s own guide says body composition results are influenced by how much water is in your body, and asks you to drink plenty of fluids and avoid exercise beforehand. Yet preparation advice is not the same everywhere. Canopy’s service page says no preparation is needed, while Form Imaging asks for no food or drink for two hours before the scan and an empty bladder.

My advice: get the preparation instructions from your clinic, write them down, and repeat them exactly next time. Same clinic, a similar time of day, the same meal and the same rest from training. Otherwise some of the “muscle” you gained may say more about your water bottle than your gym work.

For what to wear and bring on the day, our appointment checklist covers the basics. Then book the first scan with the second one already in mind. If you are also weighing a full-body MRI, read our radiologist’s view of full-body MRI in NZ first.

Sources and review

Reviewed 30 September 2026 by Dr Mark Bekhit, radiologist, against the Health NZ DEXA page (last updated 22 July 2026), Healthify’s DEXA page and the current pages of Bone and Body Blueprint, Canopy Imaging, Absolute Radiology, Allevia Radiology, Auckland Bone Density, Sharp Medical Imaging and Form Imaging (with its Healthpoint profiles for Queenstown and Cromwell). A clinic’s page describes that clinic on the review date, not the country. The directory listings were checked live the same day.

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.
