Proudly Family Owned and 100% NZ Owned and Operated.
Fridgetek designs, installs and maintains the refrigeration and HVAC systems that keep critical operations running — precisely, reliably, and for the long term.
Professional. Reliable. Built on relationships.
FridgeTek was founded by Luke and Talija Posthuma with a simple goal: to provide reliable, high-quality refrigeration and HVAC services backed by honest advice and solid workmanship.
With more than eight years of hands-on experience, Luke has worked across commercial and industrial refrigeration, air conditioning and HVAC, building the practical knowledge needed to diagnose problems, find the right solution and get the job done properly.
As a small, locally owned business, we believe our reputation is built one job and one customer at a time. Whether it's a breakdown, repair, maintenance or a new installation, we take the same approach — understand what the customer actually needs, do the work to a high standard, and build systems that are reliable for the long term.
At FridgeTek, we're focused on building lasting relationships with our customers through dependable service, technical expertise and straightforward advice.
Values that define how we work.
Forward-thinking
We adopt the latest efficient technologies — heat pumps, smart controls, low-GWP refrigerants — before they become standard.
Reliable
Engineered redundancy and rigorous commissioning mean our systems perform when it matters most.
Technically expert
Certified engineers with deep expertise across refrigeration, HVAC and process cooling disciplines.
Customer-focused
Honest advice, transparent communication and long-term partnerships — not transactional fixes.
Quality workmanship. Honest advice. Long-term relationships.
We don't chase the quick fix or the cheap install. Every project is an engineering commitment — designed right, built to last, and supported by people who genuinely care about your operation.
