A move across the Tasman to stop welfare payments to parents who refuse to vaccinate their children.

The "no jab, no pay" policy is supported by the Labor opposition and is due to come into effect early next year.

In this country, Labour's Social Development spokesperson Carmel Sepuloni is unimpressed with the Australian approach.

She says immunisation rates in New Zealand sit at about 93 percent.

"We feel comfortable there, obviously aiming for high rates of immunisation is the key thing, but look, we're not going to compel all parents to immunise so why should we only compel beneficiaries?"
