LISTEN: Andrew Kelleher from JMIS speaks to Rachel Smalley on KPMG Early Edition

Chinese authorities busted a bank that's alleged to have assisted people in getting $64 billion out of China.

Andrew Kelleher from JMIS told Rachel Smalley there's a belief that these outflows have contributed to high real estate prices in a number of cities.

He said while we don't know if Auckland has been affected by the bank, it would be naive to think otherwise.
