Apple will contest a court order asking it to help FBI investigators access data on the phone belonging to San Bernardino gunman Syed Rizwan Farook.
The company had been ordered to help the FBI circumvent security software on Farook's iPhone, which the FBI said contained crucial information.
Auckland University’s computer science lecturer Dr Paul Ralph joined Paul Henry this morning.
In a statement, Apple chief executive Tim Cook said: "The United States government has demanded that Apple take an unprecedented step which threatens the security of our customers."
"We oppose this order, which has implications far beyond the legal case at hand."
