Clarus is one of New Zealand's largest energy groups.

Whether it’s transmission, distribution, supply or storage of energy, the companies within the Clarus group service over half a million homes and businesses of all sizes around New Zealand.

Firstgas connects over 300,000 homes and businesses with natural gas though its gas distribution and high-pressure transmission network. This essential infrastructure supports New Zealand’s economy, so the group is committed to helping customers maximise value from it.

Flexgas provides energy storage services to electricity generators, offering an important source of flexibility to the electricity system and supporting high levels of intermittent wind, hydro and solar generation.

Rockgas is New Zealand’s largest LPG retail supplier, providing fast and reliable service through a national network of branches and franchises.

Firstlight Network is the lines company supplying electricity to the Tairāwhiti and Wairoa region, responsible for keeping the lights on across 12,000 square kilometres of the East Coast.

We are also investigating innovative renewable gas technologies such as biomethane and hydrogen, which have the potential to play a part in the transition to a lower emissions energy system. First Renewables is our business leading the renewable gas work programme. We aim to provide New Zealand homes, businesses and energy-intensive industries with lower emissions gas energy options in the future.
