New Zealand is launching a trade dispute against Canada in a growing dairy backlash.

The Government's arguing we don't have as much access to the Canadian export market as promised.

The dispute is the first lodged under the Comprehensive and Progressive Agreement for Trans-Pacific Partnership.

Dairy Companies Association Chairman Malcolm Bailey told Mike Hosking this is a good move.

He says Canada has a record of entering into agreements and then finding a way to make them not work properly.
