Police are looking for Ayom Wek, 31, who has made off with nearly $2 million in alleged money laundering.
"Police investigating the term deposit scam have identified Wek as part of our enquiries," detective senior sergeant Craig Bolton said.
"At this stage, we have received five reports relating to this man, each with hundreds of thousands of dollars behind them."
A border alert is in place if Wek attempts to leave the country.
"Wek is believed to be based in Auckland Central and we understand he remains in the country."
Wek's offending totalled about $1.8m, Bolton said.
The Financial Crime Unit has several warrants to arrest for significant fraud.
"As part of our ongoing enquiries, we are now seeking his whereabouts in regards to these significant reports of fraud and warrants to arrest have been granted."
The public is asked to stay cautious and notify police of any information regarding the man.
"We continue to urge anyone seeking financial advice or those looking to invest in a term deposit to proceed with caution."
