The Government is working on plans to let firms to be able to buy renminbi directly when trading with China.
Prime Minister John Key is in China with a trade delegation and met President Xi Jinping on Sunday.
Mr Key said he wants to remove the complexities in buying and selling the Chinese currency to ease the growing flow of trade between the two countries.
As part of an opening trade in the Chinese currency, Beijing let domestic companies pay for imports with renminbi in 2011 rather than go through the costly process of buying US dollars to pay for them.
But financial intermediaries, such as banks, are still largely barred from dealing in yuan, leaving exporters with an illiquid market to cash up their yuan receipts.
