The associate health minister, Julie Anne Genter, said New Zealand has offered advice and assistance and stands ready to help in any way.
"I understand Samoa is working through its response and authorities have requested that any support from New Zealand, waits until Samoa's needs are more clear," Ms Genter said.
Epidemics were declared in Samoa and Tonga this week, and both were spread from New Zealand, where an outbreak in Auckland has affected nearly 2000 people.
