A new union body in Tonga called the Friendly Islands Public Service Association says it aims to push the government into passing legislation to protect the rights of workers.
FIPSA is scheduled to be operating by November.
Spokesman, Fotu Fisi'iahi, has been in New Zealand seeking assistance and building connections with the Council of Trade Unions there.
Mr Fisi'iahi says the recent public sector strike showed there was a need for a permanent group to represent workers.
He says FIPSA's top priorities will be to encourage the government to pass legislation that was tabled more than 10 years ago.
"One of our first priorities is to push for the government to enact an employment act in order to protect the interests of the workers, especially in the occupational, health and safety aspect of it, plus the welfare aspect."
