How the NZ Radiology Directory Is Built and Updated

Radiology Clinics NZ is built from a structured clinic inventory rather than from a loose list of web pages. The directory starts with official brand and clinic sources, then uses a conservative checking workflow before clinic names, addresses, contact details, and scan services are promoted into public pages.

The live directory currently tracks 341 published clinic pages and uses a record of where each scan was named for core scan types such as MRI, CT, ultrasound, X-ray, and PET/CT. That means a clinic page can distinguish between scans a clinic names on its own page, scans named only across a brand, and scans we have not found stated anywhere.

Primary sources

The strongest sources are official brand branch pages, official booking or location pages, and public hospital or Health New Zealand service pages. Healthpoint and other secondary sources can help resolve gaps, but the preferred source for clinic services, address, and phone information is the clinic or brand itself.

How scan information is checked

Each core service is stored separately. A service may be marked as listed at branch level, provisionally supported at brand level, not stated, or, where the clinic’s own page lists its scans and a scan is not among them, not listed at that clinic. Public pages use those structured fields first, and only fall back to text-based clues when no listed service map exists for that clinic.

Researchers can download the whole directory as a CSV file and read the citation and licence terms on the Data and research page.

How duplicates and old brand names are handled

Radiology brands sometimes rebrand, merge branches, or publish multiple pages for the same site. The directory treats those cases conservatively. A possible duplicate is checked against the live post status, public URL, source page, address, phone number, and intended successor before redirects or cleanup are considered.

What the directory does not promise

The directory is informational. It does not confirm referral eligibility, current wait times, appointment availability, pricing, funding, or whether a scan is suitable for a patient. Patients should confirm those details with their referrer, brand, insurer, or clinic before booking.

Update workflow

Updates are handled as a refresh cycle: export the current live inventory, collect source candidates, build a reviewed master dataset, verify exceptions, import safe changes, and run duplicate checks afterward. This gives the directory a repeatable process rather than one-off manual edits.

The service map currently covers 12 tracked service labels across the public inventory, with a clinic page naming it preferred wherever possible.
