The Serious Fraud Office says Teremoana Kimiangatau has been sentenced in Manukau District Court to three years and two months' imprisonment for a fraud committed against her employer, Auckland International Airport Ltd.

Mrs Kimiangatau had worked at Auckland International Airport for 18 years and pleaded guilty to three representative charges of obtaining by deception. The amount involved was approximately $1.8 million.

The Serious Fraud Office says its investigation into Mrs Kimiangatau found that she had transferred funds from the Auckland International Airport Limited bank account to her own account. She had facilitated this by changing client bank account numbers to her own within the airport's accounting system.

The matter was referred to the SFO in February 2016.
