A legal expert says New Zealand doesn't allow interviews with jurors, to allow for open and honest discussion in the jury room.

An interview with one of jurors on Bill Cosby's sexual assault case has been aired on ABC in the US.

Victoria University media law expert Steven Price told Larry Williams there's a reason we don't allow that over here.

He says if jurors feel they'll be criticised or made fun of for what they say in the jury room, it could hold back their free and frank discussion.
