Convicted axe-murderer John Ericson has been put back behind bars amid fears he presents an "undue risk to the safety of the community".
John Frederick Ericson, 57, killed his wife Sandra in 1999 by striking her in the back of the head with a tomahawk 22 times while she slept.
The Blenheim man called police after the attack and admitted killing his wife but later said he had no memory of it.
He plead guilty to the murder in 2000.
He was released on parole last year after 19 years in jail, but was locked up again this week after the Department of Corrections applied to have Ericson recalled to prison.
