- Security at Prime Minister Helen Clark's home in Auckland has been reviewed by police after two breaches in the past four months.
Details of the incidents came to light on Sunday, Radio New Zealand reported.
In one case, graffiti was left on the building, and in another, a man who had robbed a nearby store hid in Clark's garden while he changed his clothes.
Police have looked at procedures and Diplomatic Protection Squad staff have been debriefed.
They have not revealed details of the review, only saying they do not want to compromise future security arrangements.
Police national operations manager, Superintendent Tony McLeod, says there was never a direct threat to Clark from the incidents and her safety was not compromised, Radio New Zealand said.
