Three others along with Kim Dotcom were arrested in January 2011
New Zealand has called for an inquiry into spying on Megaupload founder Kim Dotcom by the Government Communications Security Bureau, leading to his arrest in January 2012.
Kim Dotcom was arrested together with three others in January, following a raid by police after the US Federal Bureau of Investigation (FBI) had ordered and charged him of internet piracy and breaking copyright laws.
In June 2012, a New Zealand court ruled that search warrants used in the raid on Dotcom’s home earlier this year, were illegal .
New Zealand Prime Minister John Key said that the country expects its intelligence agencies to operate always within the law.
"Their operations depend on public trust," Key said.
"I look forward to the Inspector-General’s inquiry getting to the heart of what took place and what can be done about it."
"Because this is also a matter for the High Court in its consideration of the Megaupload litigation, I am unable to comment further."
The FBI accuses the Megaupload as a firm has gained a profit of $175m since 2005 had been involved in copying and distributing music, films and other copyrighted content with no authorisation.
Megaupload has also requested for dismissing US criminal charges against the firm disagreeing that the US has no jurisdiction over the service operated in Hong Kong.
Kim Dotcom is a German national and currently a resident of New Zealand.
