Interlock Celebrates its Golden Anniversary


The Interlock brand was founded by Ron Davis (an English Lithographic Colour Retoucher) and Stuart Young (a Registered Master Builder) in 1961 when they registered the “Interlock Fencing Company Ltd”.

Located in Stuart’s backyard workshop, the early days of Interlock saw many trials and tribulations. The market for Interlock fences was quickly exhausted and the business almost failed on a number of occasions. However, the entrepreneurial spirits of Ron and Stuart saw them come up with a product that would take off in both local and international markets; namely a non-wearing nylon friction joint for the 4-bar Friction Stay. This invention was quickly patented, and thankfully enabled the company to move from Stuart’s backyard in 1969 to a factory in Miramar, Wellington.

From there “Interlock Industries Ltd.” continued to expand and excel, winning numerous awards in the areas of quality, innovation and excellence in export. The company was also heralded by academics and practitioners alike for its best practice in the quality of employee working life and teamwork. These three factors, quality, innovation and teamwork are in Stuart Young’s eyes the critical elements of the company’s success.

The operations of Interlock Industries were eventually relocated to Albany in Auckland, where it remains today. In 2001, the company was acquired by the ASSA ABLOY Group making this year ASSA ABLOY New Zealand's 10th Year Anniversary.

On February 25th 2011, Stuart Young, along with 30+ other ex-Interlock personnel, joined current ASSA ABLOY staff to celebrate the 50 Year achievement. Ex-Interlock employees were whisked away on a site tour upon their arrival in Albany before everyone came together for a company photo. Stuart Young (co-founder), Tony Gledhill (ex-Interlock Director) and Ken Dick (current General Manager) addressed the crowd to commemorate the past and paint a picture for the success of ASSA ABLOY New Zealand in the future.

A casual lunch, drinks and copious amounts of cake were enjoyed by all. There was plenty of laughter to be heard as old colleagues were given the chance to catch up with each other and reminisce about ‘the good old days’ of Interlock.
