The new vessel was designed by Australian company OceanTech, under the direction of Westfleet chief executive Craig Boote.
Designed specifically for challenging New Zealand fishing conditions, the new boats will enable the use of Precision Seafood Harvesting technology, which does away with traditional trawl nets to allow fish to be landed alive and in better condition.
The new vessels will be more fuel efficient, require less maintenance and are designed to handle rougher weather.
"This is hugely important for our customers, because it means they can continue to expect a more consistent supply of high quality seafood during adverse weather conditions" Carrington said.
Aimex managing director Steve Sullivan said the contract gave Aimex the opportunity to build capability and would benefit the local economy.
The first trawler is due for completion in mid-2016 and other vessels in the seine and longline sector will follow, Carrington said. All up, Aotearoa is served by 65 vessels in the inshore fishery.
Aotearoa Fisheries will assist individual operators with transitional funding, long-term access to quota, financing and business support.
Aotearoa Fisheries comprises AFL Inshore, AFL Aquaculture and Prepared Foods. In addition, Aotearoa, along with Japan's Nippon Suisan, are 50/50 owners of one of New Zealand's biggest fishing companies, Sealord.
