Finance Minister Bill English is off to China for a first-hand look at its economic and financial situation.
China is a vital export market - it was the largest until slumping dairy exports put Australia back on top earlier this year.
Its economic growth has slowed and in recent weeks the stock market has been chaotic, with the Government imposing strict trading conditions.
Mr English left last night and returns at the weekend after visiting Beijing and the high growth areas of Chengdu and Chongqing.
He'll meet senior counterparts in Beijing to discuss the latest economic developments.
"The visit will also provide a valuable opportunity to get an on-the-ground sense of the current situation in the Chinese financial system and better understand any potential flow on effects for New Zealand," he said before leaving.
