New Zealand has signed an agreement of more than US$12 million with the Pacific Islands Forum Fisheries Agency (FFA).
The five-year arrangement aimed to support the sustainable management of the Pacific's offshore fisheries.
The money would give planning certainty to an industry which contributes around $1 billion dollars to Pacific Island economies annually.
And would help support a wide range of important services including training, technical advice, governance and fisheries surveillance.
New Zealand High Commissioner to the Solomon Islands Georgina Roberts said keeping the region's tuna resources healthy was a priority.

"New Zealand recognises the important contribution FFA makes to economic development and regional solidarity in the Pacific," Roberts said.
Growing social and economic benefits to Pacific people was something New Zealand has been committed to for the past four decades, she said.

FFA director general Dr Manu Tupou-Roosen thanked the New Zealand Government for its "steadfast support".
"New Zealand has always played an invaluable role for FFA - both as a founding member and as a long-standing development partner.
"We sincerely thank New Zealand for its crucial support for our work towards maintaining the largest and most sustainably managed fishery in the world," Tupou-Roosen said.
Working together with member countries ensured the fisheries sector continued to support the incomes, jobs, livelihoods and food security of the region's people, she said.
