Eight cancer groups say progress towards national screening for bowel cancer is too slow.
The groups, known collectively as Cango, say bowel cancer is a major health problem and deserves higher priority.
Cango says cancer is New Zealand's number one killer, and the burden will become even greater as the population ages.
It has released a manifesto demanding action in seven main areas by whichever party forms a government after the September election.
Cango says it supports the present Government's commitment to a national bowel-cancer screening programme, but is concerned the rollout is too slow.
It says the next Government must ensure a pilot programme under way in Waitemata is completed to deadline next year, and that the workforce needed for full national screening after that is ready.
