“Einstein said, the height of insanity is doing the same thing over and over again expecting a different result. However I think we are at a time of such rapid change in all aspects of life, that I modified it. The height of insanity is doing the same thing over and over again and expecting the same result. As the world shifts its gears to embrace change around doing better and climate change, we all have a choice, be the change, chase the change or get left behind by the change.”

Apex Wiring Solutions

Simon Waldren

Hi there, I am Simon, and my passion and expertise is in Modular Wiring Systems and Solutions. I believed in this so much that I chose to move all my family over from the UK in 2012 to set up my business bringing these systems and products to the market here and in Australia.

I particularly love being part of the advancement of the industry through activity and doing rather than just talk. Since moving over from the UK, I have dedicated my efforts to introducing the application of this technology in the construction industry, with varying degrees of success. Our team has delivered success in our key focus industry sectors and markets, we all enjoy learning from each and every experience that we have on our journey.


I am more than happy to talk about the upsides and the downsides of our experiences openly. I will give an honest insight of our modular journey and how it is succeeding whilst being bashed, criticised, attacked, knocked, and supressed by mainstream and some of the competition. You know you are doing something right when you are being attacked so obviously and consistently by competitors, haters, and conventional industry stalwarts.

We need to be disruptive to challenge norms and help bring about changes.

I look forward to being at COLAB24 in Auckland and listening to some industry changing people talk on their journeys and experiences.
