Surgery Wait Times NZ: Public Waiting Lists
Two separate waits sit between a New Zealander and publicly funded surgery. The first is the wait to see a specialist. The second is the wait for the operation once a specialist has scored you above your district's threshold. Most published commentary covers only the second.
This guide sets out the national numbers, the threshold system that decides whether you join a list at all, the procedure-level waits that Health New Zealand has released, and links to what each of those procedures costs privately.
How long is the wait for elective surgery in New Zealand?
At December 2025, 64.5 percent of New Zealanders received elective treatment within four months, against a Government target of 95 percent. The Department of the Prime Minister and Cabinet's target factsheet for the quarter ending March 2026 records that figure as a 5.3 percentage point improvement on the same quarter a year earlier, when it was 59.2 percent, and a 1.4 percentage point decline on the previous quarter's 65.9 percent, which it attributes to seasonal patterns.
Volume is rising even as the percentage moves slowly. The same factsheet records 51,513 people treated from the elective waitlist in the quarter, up from 46,841 in the same quarter the prior year. The Government's status assessment for the target is "Feasible".
The Office of the Auditor-General's 2025 report on planned care puts that in longer context. It found that the proportion of people receiving planned care treatment within four months has been in decline since 2017, and that the 95 percent target is set for 2030 with interim milestones of 63 percent by the end of 2024/25, 67 percent in 2025/26 and 71 percent in 2026/27.
| Measure | Figure |
|---|---|
| Target | 95 percent treated within four months |
| Baseline, September 2023 | 62.0 percent |
| Current, December 2025 | 64.5 percent |
| Treated from the elective waitlist in the quarter | 51,513 |
| Milestone for 2026/27 | 71 percent |

The score that decides whether you get on a waiting list
Being referred to a specialist in New Zealand does not put you on a surgical waiting list. Specialists score patients using national Clinical Priority Assessment Criteria tools that run from 0 to 100, with a higher score indicating greater need, and a patient only joins a treatment waiting list if they meet or exceed a pre-determined threshold score.
The Auditor-General's report is explicit about what sets that threshold. It states that where the threshold sits "depends on both clinical need and the resources available to meet demand for health services". In other words, the bar moves with capacity, not only with medicine.
For hip and knee replacement, the practical effect is a wide regional spread. RNZ reported that patients in Tairāwhiti need a score of 20 to qualify for surgery, Canterbury requires 50, Southland requires 70, and Wairarapa sets the highest bar in the country at 80. Health New Zealand has finished standardising the entry threshold for cataract surgery but, as at that reporting, had not yet done so for orthopaedics.
Once on a list, patients are ordered by urgency category. The Auditor-General's report gives one district's expected timeframes as 15 to 30 days for urgent patients, 31 to 90 days for semi-urgent and after 91 days for routine.
Wait times by procedure
Waits differ enormously by procedure and by hospital, and the published data is procedure-specific rather than national. The figures below come from Health New Zealand data released to RNZ and from Health New Zealand's own colonoscopy target reporting.
Knee replacement. As at the end of January 2025, average waits ranged from 107 days at Christchurch Hospital, the only hospital in the country meeting the four-month target, to 443 days at Grey Hospital and 721 days at Southland Hospital. Middlemore had the largest list in the country at 654 people with an average wait of 223 days, and quoted an average 47-week wait for the first specialist appointment at its Super Clinic. See our guide to knee replacement costs.
Hip replacement. No hospital was meeting the four-month target on the same data. The shortest average wait was 128 days at Hawke's Bay Hospital. Southland's 2024 average was 454 days. See our guide to hip replacement costs.
Colonoscopy. As at May 2026, 20,450 people were waiting and almost 60 percent had waited longer than the recommended time. The targets are 90 percent of urgent cases within two weeks, 70 percent of non-urgent within six weeks and 70 percent of surveillance within twelve weeks. In May, urgent cases reached 82 percent, while fewer than half of non-urgent and surveillance procedures were done within the recommended time. See our guide to colonoscopy costs.
Cataract surgery. Cataracts are the one specialty where the national entry threshold has been standardised. Additional capacity is being added: expanded eye care services for the Hutt Valley and Porirua are delivering 20 to 25 cataract surgery sessions each month, freeing theatre capacity at Kenepuru and Wellington Hospitals for more complex procedures. See our guide to cataract surgery costs.
What the private alternative costs
Going private removes the queue but transfers the whole cost to you or your insurer. The published figures below are the ones cited in each of our procedure guides, drawn from insurer claims data and provider price lists rather than estimates.
| Procedure | Published private cost | Source |
|---|---|---|
| Colonoscopy | $2,100 to $3,600 | Southern Cross claims data (2022/23) |
| Knee replacement | $26,300 to $32,000 | Southern Cross claims data (2022/23) |
| Hip replacement | $25,100 to $30,800 | Southern Cross claims data (2022/23) |
| Cataract surgery, per eye | From $5,463 with a standard lens | Published surgeon price list, Auckland |
| MRI scan | $1,056 to $2,252 by region scanned | Published radiology price list, Waikato |
| Wisdom teeth removal | $200 to $800 or more per tooth | Published dental cost guide (2026) |
| Laser eye surgery, per eye | $3,200 to $3,600 | Published clinic survey (2025) |
| IVF cycle | $15,815 or more in base fees | Published clinic price list |
Two of those are not insurable. Laser eye surgery and IVF are excluded by policy wording in this market, as each guide explains. The others are generally covered by comprehensive health insurance, subject to excess, prior approval and pre-existing condition rules.
How Health New Zealand uses private capacity
Health New Zealand buys private capacity to reduce the public backlog rather than treating public and private as separate systems. The Elective Boost programme partners with the private sector through to June 2026 to deliver an additional 21,000 hip, knee, cataract and other procedures.
That approach is already visible at procedure level. In the 2024/25 financial year, 990 hip replacements and 1,061 knee replacements were outsourced to the private sector. For colonoscopy, about 30 percent of the 67,500 publicly funded procedures completed in 2023 were outsourced to private providers, and officials describe outsourcing as "a long-term tool, not a stop-gap measure".
The practical consequence for patients is that being treated in a private hospital does not always mean paying. It can mean the public system bought the slot.
What this means when you are choosing cover
The wait times above are the reason most New Zealanders give for holding health insurance, but the cover only helps if the condition is not already a pre-existing one. Every mainstream policy in this market excludes pre-existing conditions unless they have been disclosed and specifically accepted, which means insurance is bought before symptoms rather than after a referral.
The second thing to check is what the policy does with diagnostics, because a scan often sits between you and the surgical decision. Some plans only pay for imaging that is tied to a surgical event, which is covered in our guide to MRI scan costs and cover.
