The Government is strongly opposing proposed changes to infant formula laws.

Minister from Australia and New Zealand will meet this week to discuss a 400-page proposal, which would overhaul baby formula regulation - including labelling laws.

Some groups fear it would cause plain-packaging and cripple New Zealand's exports.

Finance Minister Nicola Willis says the impacts would be too severe.

"There is no way that we can support a provision which would wipe potentially $2 billion of export revenue away."
