The half-brother of Levin schoolboy Alex Fisher is due to be sentenced for his murder.
Eric Baden McIsaac, 26, admitted murdering the 10-year-old at Waitarere Beach last October at the High Court at Palmerston North in May.
Alex's body was found in sand dunes at Waitarere Beach following an extensive three-day search.
He was last seen alive with McIsaac at the Waitarere Four Square store on October 5.
His disappearance prompted a search with more than 100 people including police, search and rescue teams, and defence personnel involved in looking for the missing schoolboy.
His body was eventually spotted by a helicopter on October 8 near beachfront baches at Waitarere Beach, northwest of Levin.
He was found wrapped in a blanket and had suffered a head injury.
McIsaac, who also pleaded guilty to possession of a knife in a public place and the burglary of a Waitarere Beach property, will appear for sentencing on Friday.
