The union for nurses is defending the New Zealand Nursing Council against allegations it is unfairly targeting migrants from the Philippines.
The council is concerned an increase in the number of nursing courses in the Philippines could be affecting the quality of nurses.
It plans to send representatives to the Philippines to discuss the matter with Filipino authorities.
The Migrant Action Trust says the council is showing a lack of understanding and is accusing the council of unfairly targeting Filipion nurses.
A spokesperson, Agnes Granada, says many people in the Philippines choose to study nursing as a second tertiary qualification, but that does not reduce the quality of their degree.
Ms Granada says there should be migrant representation on the Nursing Council so it can understand how different curriculums work in different countries.
However, New Zealand Nurses Organisation chief executive Geoff Annals says the council needs to ensure that every nurse practising in this country meets New Zealand registration requirements.
However, Mr Annals says some nurses from the Phillipines may not, given the proliferation of new schools there.
