The lawyer for a Kiribati man who lost his bid to be regarded as a climate change refugee hopes to have his case looked at by the United Nations in the new year.
Lawyer Michael Kidd said Mr Teitiota, his wife and their three New Zealand-born children were struggling to settle and wanted to look at moving to Timor-Leste.
The family was living with Mr Teitiota's brother-in law in Kiribati, Mr Kidd said.
The children have been struggling to adapt to life there and Mr Teitiota's son has been in particularly bad health, he said.
"His immune system is having difficulty coping with the fact that most of the fresh water comes from reservoirs that are invaded by salt and that are contaminated by human waste.
"I mean, if he was to become seriously ill, I don't think it would make the New Zealand government look very good, would it?"
Mr Kidd said he would be laying a complaint with the UN Human Rights Council and hoped to improve the treatment of those affected by climate change.
"There's a lot of awareness, at least in the European Union, that this needs to be looked at very seriously.
"The New Zealand government seems to be dragging its feet on providing refuge for people being displaced by climate change. The Fiji government has done a lot."
Fiji sold 20 square kilometres of land for Kiribati to cultivate in a measure to increase food security.
Fijian prime minister Frank Bainimarama also told Kiribati president Anote Tong his people should not fear being climate change refugees, and Fiji's doors were open.
