The policy, which was endorsed by cabinet in 2020, aims to maximise the ability of workers to move overseas to get jobs.
Thousands of Tongans are employed in labour mobility schemes in New Zealand and Australia in horticulture, meat processing, construction, tourism and hospitality.
Tonga's Prime Minister Pohiva Tu'i'onetoa said his country benefitted greatly from labour mobility.
The greatest benefit, he said, was in providing employment opportunities for the unemployed and the poor so that they could improve their standards of living.
