Making gas better for all New Zealanders

Firstgas Group has acquired businesses that have been driving innovation in New Zealand’s energy sector for nearly forty years. Investigating innovative technology is part of Aotearoa’s journey to cutting emissions, and we firmly believe that the sustainability, reliability and affordability of gas will help get us there. That’s why we continue to invest in our operations and explore new, better ways of delivering gas to all New Zealanders, now and in the future.

SHAPING NEW ZEALAND’S GAS FUTURE

Graphic Boots Clearcut

The assets managed by Firstgas Group have been at the forefront of innovation in New Zealand’s energy sector for nearly forty years. Through our leading companies First Gas, Rockgas, Flexgas and Gas Services New Zealand, we have the future of gas in our sights – while ensuring Kiwis get the natural gas and LPG they need today, safely and reliably.

Firstgas

Based in the energy-rich region of Taranaki, Firstgas connects natural gas to homes, businesses and large industry through more than 2,500 kms of high-pressure gas transmission pipelines across the North Island. We also own 4,800kms of gas distribution networks in the North Island. Through our transmission and distribution networks we connect 300,000 homes and businesses to gas.

Rockgas

Rockgas is New Zealand’s largest LPG retailer, serving over 116,000 customers from nine branches and 34 outlets across the country. Reliable and highly efficient[1], LPG offers big savings over electricity[2]. We make sure it’s available wherever, however and whenever our customers need it – whether that’s delivering gas bottles to homes and baches or providing LPG tanks to businesses. With a reputation for quality, Rockgas won Canstar Blue’s “Most Satisfied Customers in Bottled Gas” award in 2020,and given five stars by its customers for overall satisfaction, value for money and cost clarity.

Flexgas

Flexgas owns and operates Taranaki’s recently expanded Ahuroa gas storage facility. By providing energy storage at scale, we help major gas users manage varying demands – which ultimately means our customers can better manage their energy supply and demand variability for years to come.

Gas Services New Zealand

Gas Services New Zealand is the operations and maintenance company who makes sure our gas is delivered safely and continuously. While they don’t have a retail presence, they’re critical to keeping the lights on and the gas flowing around the clock.

Innovation

A history of Innovation

The assets owned by Firstgas were established in 1972 and Rockgas has been around since the 1930s.

Over that time we’ve worked hard to build and maintain a reliable gas pipeline and distribution network in New Zealand, including the Maui pipeline and the Ahuroa Gas Storage Facility – which we recently upgraded to provide increased gas storage and more flexibility for our customers.

The role of gas in a low carbon future.

We believe energy storage, like that provided by Ahuroa, will play a vital role in Aoteoroa’s low-carbon future. It supports the generation of renewable electricity (particularly in the winter months and over peak demand periods) and is becoming even more important with the addition of renewable wind and solar generation capacity.

Today, Firstgas Group companies provide natural gas and LPG to more than 430,000
residential, commercial and industrial customers across Aotearoa. Our vision? To continue to lead the delivery of New Zealand’s energy in a changing world, providing affordable, accessible energy to Kiwi families and businesses.

To do this, we’re exploring how we can deliver greener gas and support New Zealand’s goal of zero carbon emissions by 2050.

Innovation through partnerships

Firstgas recently partnered with Gourmet Mokai – the NZ grower and exporter of greenhouse tomatoes – to supply and install a new 6MW LPG-fired hot water boiler in their greenhouses.

 

Gourmet Mokai

Firstgas recently partnered with Gourmet Mokai – the NZ grower and exporter of greenhouse tomatoes – to supply and install a new 6MW LPG fired hot water boiler in their greenhouses.

Because it is clean burning, LPG flue gas can be safely introduced into Gourmet Mokai’s greenhouses, where the small amount of CO2 produced increases plant growth and productivity. Meanwhile, the heat from the boiler provides efficient heating certainty in the months when their geo-thermal steam heating is down for maintenance.

Our transition

Driving New Zealand’s zero carbon target

A member of the Climate Leaders Coalition of New Zealand, Firstgas Group is committed to helping Aoteoroa achieve its target of net zero emissions by 2050.

Firstgas wants to make gas greener for Kiwis by carrying hydrogen and biomethane through our gas pipelines. Our goal is to achieve 100% zero carbon gas by 2050, with the first step being a transition to delivering 20% hydrogen by 2035.
