The survey shows 18 per cent of people putting health care at number one. This is especially true for women with 23% believing it's the top priority.
It's also an issue felt strongly in the South Island, where almost a quarter of people who answered the survey put health care first.
Health is a big ticket item for the Government, spending more than 16 billion dollars each year, with another billion dollars a year added in the latest budget.
Jennifer Lees-Marshment from Auckland University believes the Vote Compass results means the parties vying for votes this election need to take heed of the issue.
"This is a major challenge for the parties to respond to this sudden realisation that health is a big issue," she said.
1 NEWS Vote Compass is live online right through the election campaign.
