"Ask Wayne what the future holds, and he'll tell you what he won't be doing - retiring," Mr Cooper said.
"His loyal staff don't seem to be going anywhere either - he and Bev can name several that have been with the company for 25 years plus."
The company was started by Wayne's dad Ted in the early 1950s. Wayne came into the business picture when he was just 13, cleaning concrete mixers and caravans.
He did work for Dave Culham for a spell but returned to Cowley's.
Wayne and Bev have owned Cowley's Hire Centre since 1988, after Ted died in 1985.
In 1990, they moved from Manse St to their Commerce St base and now the next generation, Lucretia and Trent (Cowley's Party Hire manager) are involved in the business.
And as well as the Commerce St headquarters, the business has expanded to include depots in Ruakaka, Kamo, Kerikeri, and a party hire depot in Kioreroa Rd, Whangarei.
The Kamo business is moving from Clark Rd to Great North Rd as part of the ongoing changes that have helped make Cowley's Northland's number one locally owned hire company.
