An extra 10,000 Chinese tourists will holiday in Queenstown in early 2018, after the New Zealand government won a major contract to host the winners of a sales competition for a major Chinese company.

It is expected to inject $50 million into New Zealand's tourism economy.

Prime Minister John Key made the announcement at a signing event in Shanghai, as he wrapped up a week-long trade trip to China that aimed to upgrade New Zealand's free trade agreement.

Under the new contract, Amway China will see their top sales people flown to New Zealand as a reward for their hard work.
