These freezers were requested by the islands under the Fisheries Development Facility Fund's (FDF) Pae Enua Tokerau Support Grant.
The grant is designed to provide small injections of funding assistance for each of the five Pae Enua Tokerau, up to the value of $10,000 each year.
The FDF is a payment on behalf of the Crown that distributes more than $150,000 each year to fishing associations and local fishermen to support food security and small scale fishing ventures in Rarotonga and the outer islands.
The ceremony was held at the Avatiu wharf and prime minister and Marine Resources minister Henry Puna delivered the keynote address.
"You're on the frontline and you need to be supported so our own people can benefit from our fisheries resources," said Puna.
He added that it was just the beginning of more support which would be offered and he thanked MMR and its staff for its continued efforts in promoting programmes for local fishers.
MMR secretary Ben Ponia also spoke about the freezers as a significant investment and step in the process of creating further economic opportunities for the northern group islands.
Cook Islands Fishing Association president Don Beer thanked government for its assistance to the northern islands.
Rakahanga MP Basil Hagai also spoke about the efforts that had gone into procuring the custom-built 11.4 cubic metre freezers from New Zealand.
