SeaMac Aluminium was founded in 1994 by David and Janet MacInnes. 

A small family business that started with, “if you are looking for boat windows or doors, go and see Mac”… and so the SeaMac name was born.  

In 2017 the business was purchased by their son & daughter, Shamus & Bonnie, with the support of their spouses, Alysha & Clinton.  

What started as a humble family business in the small New Zealand town of Whangarei, is now a reputable company with a global presence.  

“We have taken Dad’s 40+ years of experience in the aluminium joinery world (marine and domestic) and redesigned and enhanced it to meet modern expectations on a global scale, but with the solid business foundations he gave us.” 

Dave and Janet are now happily enjoying retirement, so lets introduce you to the ‘kids’…  

  • Shamus is our Managing Director.  

    He worked in the family business out of school for a time, until the father-son relationship needed to be just that again. He parted ways to forge his own career as a fabricator/engineer where he worked in the Oil and Gas Industry in Western Australia for a number of years, as a welding supervisor.  

    He met his wife Alysha back in 2009, they’ve since had two children, Richie and Sadie, and it was time to move home to New Zealand to raise his family.  

  • Bonnie is our General Manager.  

    Bonnie’s professional life started in the casino industry as a croupier and casino host. When the time came to leave the hospitality lifestyle, she moved to Sydney to join the corporate world as a Client Relations Manager where she remained for almost 10 years. Going on to have her children Chloe and Braxton, it was time to move home to New Zealand to be near family as well.  

    She is supported by her fiancé Clinton Hall, who has forged his own career in the marine industry as the General Manager for his family business,Oceania Marine Shipyards, Refit Services, which is how the pair met. 

  • Both Shamus and Bonnie, and their families, are keen boaties and spend a lot of their recreational time on the water, so they not only understand how to make marine specific doors and windows, they also know exactly what the demands of the marine environment are and the quality required to make them last.  

    Bonnie and Shamus started working with their Dad back in 2014/2015 (respectively) with the view to give their parents a retirement plan and take over the business.  

    Between them, they brought unique skill sets to develop SeaMac into the company it is today… four times the size of the company their parents started, and now in a 1600m² building with 11 staff. Shamus heads up all research and development and designs all of our window and door systems in-house, and we are our own prime dye holders of all our extrusions.  

    Whangarei is their home town, located 2 hours north of New Zealand’s biggest city of Auckland.  

    Whangarei is very marine focused city, with four marinas and another in development, and an entire marine precinct which has made it a hub for boaties travelling through the South Pacific, or for larger recreational or commercial workboats to come for haul out and full service maintenance.
