Hong Kong is planning to extradite a New Zealand national who has been suspected of withdrawing millions of dollars that were mistakenly deposited to his account, a report by the BBC says.

Hui Gao was arrested in Hong Kong in September this year after being on the run for two years. The New Zealander of Chinese origin is wanted on money laundering and theft charges.

The problem began when Gao asked Westpac Bank for an overdraft of NZ$100,000 ($77,000) in 2009 but the bank mistakenly transferred NZ$10 million. While Westpac discovered the blunder just days after, the firm discovered that over NZ$6 million had already been withdrawn. The polic arrested Gao as he entered Hong Kong from China in late September.

Gao has reportedly consented to be extradited to New Zealand, where he will face trial with Kara Hurring, his former girlfriend who left with him in 2009. Hurring returned voluntarily to her home country in February and will face charges in 2012 on charges of stealing, theft and money laundering. 

The application for extradition was granted 27 October. No further details were given.
