Prime Minister John Key says banks and investors in China have raised the possibility of investing money in the Christchurch rebuild.
Mr Key, who is in China on an official visit, says he has told the investors there are projects that will be operated as public-private partnerships and will have a number of partners.
He says there is no reason a Chinese company could not be part of such an arrangement and he has told the investors to look at individual projects.
"Certainly Christchurch presents one or two scale opportunities and generally this is a market that needs scale."
Mr Key says the investors have a substantial amount of money to spend, and for some "the sky's the limit."
He says investors will need to work out whether they want to invest and can make a return.
On the last day of the visit on Friday, Mr Key and the delegation will attend the first joint China New Zealand Partnership Forum.
