Labour leader Andrew Little has proposed a tax on employers who rely on workers from overseas instead of training local workers saying it was a way to make sure businesses were "doing their bit".
The 'training levy' would be imposed on businesses in areas of skills shortages, such as chefs, construction, IT and tour guides where migrant workers are used.
However, companies that could prove they were already actively training New Zealanders for such jobs would be exempt.
The proposal for a training levy is included in Labour's 'Future of Work' Commission report which is being released at the party's annual conference in Auckland today.
On The Nation, Little denied it was a measure aimed at deterring businesses from bringing in migrant labour, saying immigration would always be needed.
