The Alliance is proposing a health levy on all taxpayers mainly to fund free doctor visits and prescriptions.
Party leader Laila Harre said today the 1 per cent levy would raise $840 million and would work in a way similar to Britain's National Health Service.
A spokeswoman for Ms Harre said thelevy would be an extra 1 per cent on top of income tax payments and was linked with the party's tax policy.
The Alliance proposes significant tax cuts for people earning under $40,000 a year.
"With the exception of the United States, New Zealand is unique among comparable countries in having significant financial barriers to primary health care," Ms Harre said when she launched the Alliance's health policy.
"There is no doubt that many New Zealanders are not going to the doctor, or taking their children to the doctor, when they need to because the price is just too high."
She said hospitals were overburdened, there were third world diseases in poor communities and nearly one third of hospital admissions could be avoided by an early visit to a doctor.
