Our History

Originally formed in 1989, McKenna Stainless Fittings, known formally as J & M Mckenna, began as a family-owned and operated business in Whangarei, Northland. Over 30 years’ later, the business still operates from the same Whareora workshop where it began but as sales grew, so did the team. Today, McKenna Stainless Fittings is owned by Michael McKenna and Tavita Glassie. Both highly experienced engineers who have worked within the business, in various roles for over 20 years. Together, they use their market leading product knowledge and original business values to produce a diverse range of high quality, good value and readily available stainless steel fittings.
