Help and support for exploited migrants will be delivered in a new Government scheme.

The Government has confirmed a package of basic financial support, for accommodation and essential living costs.

It plans to stop 90-day trial periods for employers using the Accredited Employer Work Visa.

Immigration Minister Andrew Little says they're tightening the scheme meant to fill gaps by letting businesses employ offshore.

"The vast majority of employers are doing exactly that, they're doing a good job. There is a small number, a very small minority who seem to have found an opportunity to scam others."

Little says investigations into employers are underway.
