"We can compete internationally with high-end, high-quality, complex tooling," he said.
"This is because much of the machining work is done unattended and with such accuracy there is very little manual work in fitting, the sort of additional task that China excels in because of the cheap semi-skilled labour," Fenton said.
"In addition, the end result for the machined item is far superior to that of a hand-worked item ... it has big benefits to New Zealand companies to have an important part of their manufacturing process done right here," Fenton said.
Adept was set up in Fenton's garage in 1969 with a home-made plastics moulding machine.
While this was the firm's speciality, it has since diversified into other areas such as custom product development and manufacturing. It also has divisions focusing on products for the medical industry and the meat sector.
The Adept beef clip - an invention from 1977 that prevents the ingested stomach contents spilling out of a freshly slaughtered animal's neck - is used in more than 95 per cent of abattoirs in Australasia as well as in Europe and South America.
