Rex Leverett John Prole, 64, was jailed for life with the minimum non-parole period when he was sentenced in the High Court at Rotorua on Thursday.
As he left court Prole yelled out that his wife was a liar.
He had earlier admitted the murder of his third wife Robyn Prole, 57,

The Proles separated three months before the murder and a protection order was in force against Prole.
A previous court hearing had been told Prole spotted his wife collecting her mail from their letterbox and he grabbed a multi-purpose kitchen knife.
He ran out and reached through the driver's window, yelling and grabbing her. He repeatedly stabbed her in the throat, chest and stomach.
She was screaming at him that she loved him and attempted to pull herself away, but Prole continued to stab her.
A neighbour who had seen what was going on yelled at Prole to stop and called the police.
However, ambulance staff were unable to do anything to save Mrs Prole, who died from blood loss from the multiple stab wounds.
