How long New Zealanders wait for common planned operations, hip and knee replacements and cataract surgery, from specialist assessment to treatment, as reported to the OECD: the median wait in days and the share waiting more than three months. Annual from 2003.
These affect how the figures can be compared.

The attached CSV is Waiting times for elective surgery in NZ (elective-surgery-waiting-times), from OECD, Waiting times for elective surgery. Describe how each measure has changed, naming its unit and period. Treat changes in basis and missing periods as breaks. Distinguish observation from explanation. Limitations: Measures waiting after a specialist has decided to treat; it does not include the wait to see a specialist in the first place. Annual figures; Health NZ's quarterly health-target reporting (to be added) gives more recent detail.. Do not infer causation from changes during government terms.
