GASNZ – Gas Infrastructure vital to Renewable Gas Future

GasNZ* welcomes the government’s Te hau mārohi ki anamata** discussion paper’s focus on hydrogen and biofuels as future energy options and its consideration of the impacts of the transition and implications for current gas infrastructure.

GasNZ Chief Executive, Janet Carson says biofuels like biogas and bio-LPG and renewable gases like renewable hydrogen gas, are already being developed or trialled and will allow New Zealanders to continue to enjoy gas energy in their lives.

“Currently, we’re working to begin blending tomorrow’s gases into the natural gas network from 2025.

“We need to maintain the infrastructure, to pave the way for introducing biogases into the network. If the infrastructure has to be rebuilt, biogases will not happen – at least not without significant cost to the people using it.

“The technology exists to supply a carbon-zero gas mix through the current natural gas network. Testing shows most modern gas appliances are compatible with blends of low carbon renewable gases and bio-LPG, and can take up to a 20% renewable hydrogen gas blend with natural gas. Blending gases will be an important part of our journey as we scale towards a renewable future.

“The economics of these options in New Zealand need to be better understood and appropriate signals through Government policy would give investors confidence to accelerate this work. We look forward to discussing potential parameters with government as part of the consultation process.

“Gas is a fuel in transition, and the New Zealand gas sector plans to be very much a part of carbon-zero gas supply.  It just needs the opportunity – and time – to do so. Ensuring that we maintain the value of the infrastructure is an important part of this” she said.


*GasNZ represents the Gas Association of New Zealand and the LPG Association of New Zealand. Its focus is to facilitate a safe, effective and sustainable industry. It advocates for the sector as it moves to a low carbon renewable gases future. You can find out more information at
