New Zealand foreign affairs officials say they have not heard from Nauru about the help Wellington gave to one of the Republic's politicians which allowed him to flee the troubled Pacific state.

Roland Kun is back with his family in Wellington after getting New Zealand citizenship on humanitarian grounds, opening the way for Kun to leave Nauru on a New Zealand passport.

A spokesman for the Ministry of Foreign Affairs said the Government of Nauru had not contacted it about Kun's departure.

"New Zealand has previously expressed to the Government of Nauru its concerns about the respect for the principles of the rule of law and democracy in Nauru, including the cancellation of Mr Kun's Nauru passport."


Kun arrived in New Zealand on Sunday - a year after Nauru authorities took him off a plane and confiscated his Nauru passport, accusing him of allegedly taking part in an anti-government protest.

Kun managed to get away after he obtained New Zealand citizenship - a decision a spokesman for Internal Affairs Minister Peter Dunne said was given on humanitarian grounds because of Kun's three young children here. That meant he could get a passport, which a family member delivered to him in Nauru.

Kun is married to New Zealander Dr Katy Le Roy and the family returned to New Zealand in 2014 after Le Roy's visa was revoked and she was deported from Nauru.

Kun was the primary caregiver in New Zealand. The involvement of New Zealand authorities in Kun's bid to escape is likely to further strain relations with Nauru.
