The New Zealand Prime Minister, John Key, says he will continue to raise concerns with the Nauru leadership at the Pacific Islands Forum summit this week.
Last week New Zealand suspended aid to the Nauru justice sector, citing concerns over human rights.
The Nauru Government hit back, saying New Zealand had been misled and was interfering in the island's domestic affairs.
Mr Key says he is confident the steps taken were the right ones, but he intends speaking with Nauru in Port Moresby.
"Don't know if it will be awkward but we will certainly be having a discussion. And personally I think the decision the Minister of Foreign Affairs reached was the right one."
Mr Key departs for Port Moresby this morning
