Definitions
The number of new cancers reflects the number of primary tumours rather than the number of individuals with cancer.
Data calculation/treatment
Unless specified in data by age group, rates are expressed per 100,000 population and age-standardised to the WHO World Standard Population. The population is based on official estimates as at 31 December.
Limitations of the data
Caution is advised when interpreting rates derived from small numbers as they may fluctuate markedly from year to year.
Exclusions
Multiple cancers with the same site and same morphological group are excluded.
Changes to data collection/processing
In these tables, Te Whatu Ora Health New Zealand extracted data for new cancer registrations between 2013 and 2022 and recalculated the rates for all years to reflect ongoing updates to data in the New Zealand Cancer Registry and the revision of population estimates from Stats NZ. These are updated annually, and more significant revisions are made after each Census.
