Prime Minister John Key is defending the Government's decision to allow Kim Dotcom into the country.
His comments come after New Zealand First leader Winston Peters called for an "immediate inquiry" into the decision to grant Mr Dotcom - previous Kim Schmitz - residency.
The native German was granted residency in 2010 under the "high-investment category", after putting $10 million into government bonds and making a large donation to the Christchurch earthquake fund.
However Mr Peters said it is hard to understand how Mr Dotcom passed the "good character" requirements for New Zealand residency, given he had previous convictions.
Mr Dotcom told the Herald on Sunday last year he was convicted for "hacking" under juvenile law and for insider trading because of ignorance about a share-trading law. Both convictions were more than 10 years ago and had been wiped by Germany's clean-slate law, he said.
