New cases of malignant neoplasms of the colon, rectum and rectosigmoid junction registered in New Zealand

The number of new cancers reflects the number of primary tumours rather than the number of individuals with cancer.

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.

Caution is advised when interpreting rates derived from small numbers as they may fluctuate markedly from year to year.

Multiple cancers with the same site and same morphological group are excluded.

In these tables, Ministry of Health extracted data for new cancer registrations between 2009 and 2018 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.
Please note that Stats NZ recently revised their population estimates for the period back until 2006, based on information from the 2018 Census. This will affect rates for a number of cancers, particularly for Māori. Therefore, rates presented in this publication cannot be compared with those in previous editions.
