New Zealand has joined a global call to drink Australian wine to send a message to China

China has slapped tariffs of up to 212 per cent on Australian wine - as part of an ongoing stoush between the two countries.

Labour MP Louisa Wall is part of the Inter-Parliamentary Alliance on China who have launched the campaign urging people to buy a bottle of Australian wine in December.

She says some of the tariffs they're trying to impose isn't fair.

Wall says as a collective of over 200 MPs globally what they're trying to do is support each other - she's categorised it as mates supporting mates.
