We’ve come a long way in 70 years and today we have a permanent construction workforce of over 350. But our family values, respect for people and drive for quality remain the same.

Our People

As a family-owned firm we know about loyalty and rewarding talent and hard work. We have a positive culture and are always looking for people with drive and ability to join us.



The built environment contributes up to 20% of New Zealand’s greenhouse gas emissions. At LT McGuinness we want to lead the way in reducing that number to net-zero. 

We want to become the leader in low carbon construction, partnering with our supply chains, design teams and sub-contractors to advise our clients on the best low carbon options whilst still providing them with the highest quality construction to the LT McGuinness standard. 

This strategy is just the start of our journey. It outlines the actions we are going to take over the next five years as we help lead the New Zealand construction sector to a zero-carbon future.
