From our Managing Director
Kia ora! I’m Keith Middleton, born and raised in Aotearoa New Zealand of Pākehā and Ngāti Māhanga (Waikato) heritage.
I’ve worked in specialist power engineering and professional services in rail, power, water, airports and heavy industry around the world. Over that time, a vision developed: To bring together a team of engineers and project managers with a genuine passion to contribute to a sustainable energy future.
In 2016, Middleton Group was founded in Melbourne. The company is now an employee-owned firm with more than 80 engineers and project managers in Melbourne, Sydney and Brisbane who work alongside communities and businesses across Australasia to help their transition to a low-carbon future.
We’re expanding our work in Aotearoa New Zealand and invite companies and individuals to work with us to help create a sustainable energy future for our families, our communities and industry.
Case studies
25kV AC auto transformer technical overview for KiwiRail
Auckland’s population is expected to grow rapidly, with the surrounding infrastructure requiring improvement to support the increasing demand. There are more than 21 million commuter rail journeys on the network in Auckland each year. The network also carries freight traffic to support the national freight supply chain.
Helping a glassmaker rebuild its furnace
O-I Glass (now Visy Glass) is Aotearoa New Zealand’s only glass bottle and jar manufacturing site, making about 70% of the country’s glass food and drink containers. The furnaces at the centre of the operation need to be shut down and rebuilt every 10-15 years.
A game-changer on the Western Line
Auckland’s rail network is being upgraded. Middleton Group project manager Eche Diaz was seconded to KiwiRail to help it procure game-changing traction power technology making its first appearance in Aotearoa New Zealand.

Our registrations and certifications
Middleton Group’s business in Aotearoa New Zealand is a proud member of Amotai, an organisation that links corporate procurement managers to Māori-owned businesses to grow indigenous businesses within the wider national economy.
In Aotearoa New Zealand, more than 150 government departments and agencies are obliged to dedicate at least 8% of their annual procurement spend to genuine and registered Māori and/or Pacific businesses, a policy, known as progressive procurement that many private companies have implemented too.
Our membership of Amotai allows us to forge stronger connections in the Māori economy as well as give back to indigenous-owned infrastructure companies.
