New Zealand's Corrections Minister, Peseta Sam Lotu-Iiga, is assessing the work being done to help Samoa create a more effective prison service.
New Zealand Corrections staff have been training and working alongside their Samoan counterparts since its government decided in January this year to separate the police and prison services.
The new structure means the services have separate reporting lines but the same minister.
Mr Lotu-Iiga says in the first four months they have established core practice policies, health policies and an onsite health clinic.
He says work has also gone into training and recruitment.
The initial agreement was to finish at the end of June but has now been extended until the 30th September.
Mr Lotu-Iiga will also attend the All Black/Manu Samoa rugby match.
