The police say they have had "positive feedback" from international law enforcement agencies on the way the raid on Megaupload millionaire Kim Dotcom's mansion was carried out.
The latest issue of the New Zealand Police Ten One magazine features an article with the headline "Careful planning behind Dotcom swoop".
It said the operation, which was planned for months and came after a request by United States authorities, reinforced the force's long-standing relationship with international law enforcement agencies.
The police have been accused of being heavy-handed in the raid at Coatesville at dawn on January 20. Dotcom's staff and family were rounded up outside the house and police eventually broke into a panic room where they found Dotcom, and a gun safe containing a firearm.
Dotcom and three associates were arrested during the operation that involved up to 70 police, some armed, and including the Special Tactics Group and Armed Offenders Squad, and a police helicopter.
