A young Whitianga computer nerd who pleaded guilty to being part of an international cyber-crime ring will be sentenced in the High Court at Hamilton on July 15.
He was charged with accessing a computer for dishonest purpose, damaging or interfering with a computer system, possessing software for committing a crime and accessing a computer system without authorisation.
Walker, who was remanded on bail, was to be sentenced in Thames District Court today.
Instead, the charges have been relaid indictably, and he was committed to the High Court at Hamilton for sentence.
Walker, who was in Thames District Court to hear the new sentencing date, told journalists he had nothing to say after his appearance.
His mother, Shell Moxham-Whyte, said she just wanted the case to be over with, and told Walker to say nothing to reporters.
Procedural issues meant the matter had been remanded back to the Hamilton High Court for sentencing, police said.
Walker was allegedly the mastermind of a "botnet" coding group said to have infected a million computers and caused millions of dollars of damage.
According to police, Walker -- known on-line as "Akill" -- received just under $40,000 for his part in the attacks, which included a global adware scheme and the collapse of a computer server at the University of Pennsylvania.
The investigation was carried out by the New Zealand police in conjunction with the FBI, the United States Secret Service and Dutch authorities.
