Slow progress in hunt for 'Runaway Millionaires'

New Zealand police are still to seek help from Chinese authorities to catch the Rotorua couple who fled the country with millions of dollars Westpac Bank had accidentally deposited into their account.

Leo Gao and his partner Kara Hurring skipped the country for Hong Kong after a Westpac banking error saw $10 million transferred to businessman Mr Gao's account last month.

He had asked for a $100,000 overdraft.

Most of the money has been recovered but $3.8 million was still unaccounted for, Westpac spokesman Craig Dowling said today.

Detective Senior Sergeant Mark Loper told NZPA national headquarters were putting together some documents about entering into negotiations with Chinese police on jurisdictional matters.

"So until that's done nothing will be progressing too much further."

New Zealand police were also working with its liaison officer in Beijing.
