There's concerns the figures given on Government health targets don't give the whole picture.

Numbers on cancer treatment access, childhood immunisation, ED stays and wait times improved in the latest quarter.

But Patient Voice Aotearoa's Malcolm Mulholland says the data doesn't reflect things like when patients leave ED.

He says there are also questions around the cancer target - which asks for 90 percent of patients to start treatment within 31 days of deciding it'll happen.

"Many oncologists would say - that's the wrong metric, the right metric is from the date of diagnosis to the date you are first seen by a specialist."
