Foreign Minister Murray McCully is to meet with Nauru's President on Thursday to discuss the future of aid funding after concerns about reported civil rights lapses in Nauru.
Mr McCully is due to meet with President Baron Waqa in Sydney on the sidelines of a Pacific Islands Forum meeting of foreign ministers being hosted by Australia's Foreign Minister Julia Bishop.
Mr McCully will not rule out cutting New Zealand's aid to Nauru's justice department if its new Government does not take steps to address international concerns about a series of issues in Nauru, including the expulsion of key members of the judiciary.
"New Zealand is taking the reports coming out of Nauru very seriously and this meeting is an opportunity to pass on our concerns and discuss our contribution to the justice sector in light of recent events."
Those events have included the arrests of opposition MPs for attending a protest, seizing passports, and banning the use of Facebook since the new Government came into power in 2014. Soon after it came into power Nauru's government also expelled key figures in Nauru's judiciary.
