The jury in the High Court trial of former MP Taito Phillip Field was on Tuesday listening to to a lengthy interview conducted by police investigators.
Mr Field denies 35 charges of bribery, corruption and obstructing justice.
He is accused of accepting work on a number of his properties in return for giving Thai nationals immigration assistance, while in Parliament. He denies the charges.
The jury at the High Court in Auckland is to listen to all eight-and-three-quarter hours of the police interview with Mr Field, which was carried out over two days in February 2007.
Christchurch-based Detective Superintendent Malcolm Burgess says a condition of Mr Field giving the interview was that the camera was de-activated.
