Labour is promising all New Zealanders will have access to the same level of cancer care no matter where they live.
It says it will set up a National Cancer Agency, initially costing $20 million, which will develop a national cancer plan if it is elected to government in September.
It is part of its campaign promise of $8 billion of health spending to redress what it calls the National government's $2.3b underspend in the sector.
"What really worries me is that cancer care can be a 'post code' lottery," said leader Andrew Little.
People in Auckland had a lower rate of radiation treatment than people in Wellington and those in Northland had a lower rate than those in Canterbury, he said.
