The sister who went travelling with the runaway millionaires has surrendered to police at Auckland airport today.
Aroha Hurring flew into Auckland at around lunchtime on a Cathay Pacific flight, where detectives were waiting for her at the arrivals lounge.
Ms Hurring was granted enough time to smoke a cigarette, shortly after surrendering to police.
3 News understands she had first made her own way to Hong Kong airport before phoning her family asking for help.
Detective Senior Sergeant David Harvey, of the Rotorua police, said they are still unaware why she returned to New Zealand
“I am aware she caught a flight from Hong Kong, which is understood was paid for by her family,” he says.
At the moment she is being spoken to by police officers and I can't tell you why she's come back."
Ms Hurring disappeared around two weeks ago after Westpac bank accidently arranged a 10 million dollar overdraft for an account belonging to her sister Cara and boyfriend Leo Gao.
Police are now urging the couple to follow Ms Hurring’s lead and give themselves up - along with the money.
“They both have family members in New Zealand. At some stage they may wish to come home, if they do then we'll be waiting for them on their return."
The couple are travelling with Ms Hurring's seven year old daughter Leena.
The couple have been traced as far as Hong Kong but police will not say where they believe the fugitives are now located.
The police have started to prepare documents for a formal request for assistance from the Chinese government.
BP has now removed its signs and tanks from the service station Gao was running before he made off with 3.8 million of Westpac's money.
