This report presents new information on trends and inequalities in cancer survival for 21 cancers diagnosed in New Zealand over a 13 year period, from 1991 to 2004.
These analyses are based on linking New Zealand Cancer Registry data, census records and mortality data.
The report finds that for all cancers and for both Maori and non-Maori, there was on average a 3% annual improvement in cancer survival. There was no observed widening of the gap between Maori and non-Maori although large gaps in cancer survival still persist between Maori and non-Maori for some cancers. Gaps in survival between high and low income groups were less marked than gaps by ethnicity across all cancers.
