Prime Minister John Key is defending the immigration category under which Kim Dotcom - who has been charged with internet piracy - was granted residency.
Mr Dotcom, who founded the company MegaUpload, was arrested in January on an extradition warrant from the United States and is now on bail awaiting the outcome of extradition proceedings..
He was granted residency in 2010 under the Investor Plus category, which requires an investment in New Zealand of at least $10 million.
Mr Key says the category has seen, for the most part, people coming to New Zealand who are making a real contribution.
He says having high-net-worth individuals moving here adds value.
