About natural gas

Key benefits


A natural gas home is luxuriously comfortable. That comfort comes from the glowing warmth of a natural gas flame fire, the all-over cosiness of central heating, and flued space heaters that heat fast and are very economical. You’ll love gas heating because it is clean burning and doesn’t add moisture or dampness to your home. It’s healthy and safe, with some solutions like Rinnai’s Energy Saver gas heaters holding the Asthma + Respiratory Foundation NZ Sensitive Choice stamp for asthma and allergy-aware products.

The comfort of natural gas doesn’t end with heating. Continuous flow hot water is powerful and delivers as much hot water as you need – when you need it – and it never runs out. That means there’s always enough water for everyone to enjoy a long, hot shower or a soak in the bath. Find our more about better hot water with natural gas.

Natural gas is affordable and can offer big savings over electricity. Prices have been consistently lower than electricity – around one-third the standard unit price of electricity. And they’re expected to stay that way for the foreseeable future. Even with daily fixed charges, natural gas is affordable and will almost always work out a cheaper option if there are two or more of you at home.  

If you’re currently using more than four large (45kg) LPG bottles a year, you’ll save money by converting to piped natural gas, even including the extra daily fixed charge. If you think you're paying too much for energy, find out more about saving with natural gas.

Natural gas appliances are incredibly efficient. Some appliances promote 95% efficiency and 7 star ratings – so they cost a lot less to run. And remember you can connect to natural gas for free with The Gas Hub and save around $2,000. Find out more about connecting to natural gas

Save up to 38% per year on hot water and central heating - around $490 for a family of five

Connecting to natural gas is easy. Firstly check your property is within the 40 metre zone by entering your address into our handy gas checker tool on the homepage.

When you’re ready, put an application enquiry through to our team by answering a few questions. You can find the enquiry form here. Our team will then be in touch with further questions to complete your connection application. Your connection processing begins once you’ve accepted the free connection offer terms we will send to you. You can expect your gas connection to be installed in around 20 working days after you’ve accepted those terms.

Find out if natural gas is available in your street and if your place is within the 40 metre free zone by entering your address into our gas checker on the homepage.

More often than not, it’s free to get connected to natural gas. In fact, around 95% of homes within reach of our natural gas network can get a free connection if installing hot water or central heating. You'll just need to buy your appliances and have them installed by a gasfitter. Find out more about getting a free natural gas connection.

The general rule is to allow 20 working days from the date you’ve accepted our connection offer, terms and conditions and completed sign up with an energy retailer.  Depending on weather and any emergencies that may arise, we may be onsite a day either side of the scheduled connection date.

When your gas pipe is laid, the preferred option is to dig one hole, through which the pipe is then thrusted underground to another hole next to where your gas meter will be positioned. However sometimes it’s more practical and easier to open a trench and lay the pipe. Any property that is dug up will be restored.  If we trench through concrete areas, we’ll install a temporary seal to the area and return within two weeks of the connection being completed to allow the ground to settle and then complete the final reinstatement.

Not necessarily. We don’t require anyone to be present unless there are access issues, for example locked gates, dogs etc.

We call our customers two weeks in advance of the connection date to confirm details and let them know the scheduled connection date.  Depending on weather and any emergencies that may arise, we may be onsite a day either side of the scheduled connection date.  We do our best to meet the date we've set and to keep you informed if you’ve requested to be present when the connection is being completed.

We have certain requirements and rules that we have to follow when installing gas pipes and meters.  As part of the gas connection process we’ll assess your requested meter position to confirm if it meets the requirements and rules.  We’ll talk you through the process if this is not the case. You can contact our customer team to ask where the acceptable locations around your house are for a gas meter to be placed.  As a general rule the location can be along the front of your house or no more than 3 metres down either side - but the meter needs to be away from opening windows, sources of ignition etc, so do check with us.

A gasfitter is a licensed and/or certified tradesperson who will install your gas appliances and associated gas pipework in and around your house.  Any work to install or service gas appliances must be carried out by a licensed gasfitter, and any new installations or alterations must be certified as compliant by them.

Leave gasfitting work to the experts - it's the law. 

An energy retailer is the company supply you and bill you for the natural gas you consume.  As part of the connection process, we’ll send your application to your nominated energy retailer and they will contact you to create a gas account for you. It's a competitive market and we recommend shopping around for special offers. On our get connected page you're able to request a list of local energy retailers.

For alterations to your meter box location a request must come through your energy retailer. Contact your energy retailer to discuss.

No we don’t deal with LPG - also referred to as bottled gas. Our business is in connecting Kiwi homes and businesses to the underground natural gas pipeline - and we can likely offer you a free connection! Natural gas is sometimes called mains, piped or reticulated gas. The pipelines run underground, so it's reliable 24/7 and won't run out.

Let us point you to our water heating cost comparison tool. Use this handy tool to compare different options for heating the water at your place. Compares upfront and running costs within our natural gas network regions - Wellington, Taranaki, Manawatu and Hawke's Bay -  and have the results emailed to you. It’s quick and easy. You’ll find our cost comparison tool here.

The majority of people choose natural gas continuous flow for endless hot water, high efficiency and practical space-saving reasons.  Often referred to as 'instant', 'infinity' or 'califont' hot water systems, there are sizes for any household, with many able to handle multiple bathrooms. 

If you're after a cylinder, natural gas-powered gas cylinders have an advantage as some still work during a power cut. 

Combi boilers can heat your hot water as well as your home, so maybe worth looking at if you are building new or completing renovations.

What’s not to love about having unlimited hot water on demand? It is extremely efficient and cost effective, delivering only as much hot water as you need. And because you’re only heating what you need, you only pay for what you use, unlike a cylinder which has standby losses.

Once you’ve covered the energy retailer's daily charge, you can expect to pay around one-third the kilowatt unit price of electricity or around .09c per unit for natural gas compared to 0.25c per unit for electricity.  Like endless hot water, the benefits go on and on and on….

Heating your home accounts for around one-third of your energy bill, so choosing the right heating is important. Today, you can choose from gas fireplaces, flued gas space heaters, ducted central heating, radiators and underfloor heating for you home. Flued gas heating is healthy and won't add moisture to your home, and its reliable, no matter the weather. There's a natural gas heating solution for every home and every budget - and their performance is outstanding!

If you already use natural gas for hot water, the 'per kilowatt hour' or unit cost of heating your home with gas compared to electricity is a lot cheaper - around one-third the price of electricity. 

Have a chat to a gasfitter or gas expert to find out what kind of gas heating solution would work best for your home, your lifestyle and your budget.

Well the heat pump sales people may think so, but we’re not so sure!

We talk with a lot of people at homeshows who say their heat pumps just aren’t up to scratch – going into defrost mode when it’s too cold outside, taking ages to heat, expensive to run and not heating enough of the home.

Flued natural gas space heaters, like Rinnai’s Energysaver range, are comparable to heat pumps. They are reliable no matter the weather, fast, highly efficient and won’t add moisture to your home.

But for all-over cosiness you can't beat natural gas central heating. Central heating systems can cost around the same as two heat pumps, but wouldn't you rather heat every room in your home with toasty-warmth, instead of just one or two?  There are some ducted heat pump systems in the market that perform similarly to central heating - except they can cost you a whole lot more to buy.

Have you ever wished you could connect your LPG bbq to natural gas instead so you'll never run out of gas in the middle of cooking?

It is possible to convert some bbqs to natural gas. Conversions would need to be done by a gasfitter at your expense – and the bbq would need to be certified as compliant by them. You'd also need the gasfitter to install a bayonet point in your backyard - this is like a plug for you to connect the bbq into.

Conversion kits are available via your local plumbing and gasfitting store. Not all makes and models will be able to convert, but it is worth asking so you can get even more value from your natural gas connection. Find out more about outdoor entertaining with natural gas

Many people use a natural gas-powered hob, also known as a cooktop, with an electric oven underneath. These dual fuel ovens are really common. There are options around for gas-powered ovens also.

Talk to your local whiteware store but firstly get inspired with our appliance gallery.

Not any time soon. There is plenty of gas available for Kiwi homes and businesses for decades to come.

There are 31 active oil and gas exploration permits. 22 of these are offshore. The permits cover an area nearly the size of the North Island.

Although the Government has banned new off-shore exploration permits, existing rights are fully protected, plus on-shore exploration is not banned and we expect to see ongoing oil and gas exploration for decades to come.

If you’re using natural gas at home, or contemplating connecting, we reckon its status quo for now. There’s heaps of gas available and good potential for new finds.

Absolutely. Kiwi homes connected to gas consume less than four percent of gas produced and collectively contribute to less than one percent of NZ’s total greenhouse gas emissions.  

Climate Change Minister James Shaw has strongly suggested that stopping Kiwis using gas in their homes is not a Government priority.  

More important in the decarbonisation journey are things like transitioning NZ’s transport fleet to electric vehicles. And just as importantly, the Government is looking to ensure a lot of trees are planted to counter emissions across the country.   

There are over 400,000 residential and business users of gas in NZ. Despite this, Kiwis using gas in their homes collectively contribute less than one percent NZ’s total greenhouse gas emissions.

The purists will say yes. But when you look closely, the solution for NZ’s best energy mix isn’t so black and white.

Despite being a fossil fuel, natural gas has always been a relatively green source of energy when compared to coal and petroleum.

When used directly to power your appliances at home, natural gas produces less carbon emissions than peak time electricity. 

Peak time electricity is energy generated using natural gas or coal. NZ needs peak time electricity when there is a shortfall in renewable energy. NZ produces around 85% renewable energy. Peak time electricity generated using natural gas emits about half the carbon dioxide as electricity generated by coal.

Use natural gas directly to power your hot water, heating or cooking. It makes more sense rather than using gas indirectly via peak time electricity.  It’s like cutting out the middle man to save! 

NZ is already a world leader with around 85% renewable energy - and we 100% support this.

Our renewable energy comes from hydro, geothermal, solar, wind, and biomass. We can’t fill the lakes on demand, get the sun to shine on cloudy days or call up a strong breeze to get the wind turbines spinning… you get the picture. There are shortfalls in renewable energy generation so 100% generation is a big ask. That’s where natural gas is quick to step in and generate extra electricity to keep the lights on.  

That’s also why NZ’s aspiration to be 100% renewable only applies in normal conditions – even the politicians know that a pure 100% isn’t likely in NZ and would increase electricity costs a lot.  None of us want that.

Natural gas is a great back up option to solar at home, and many gas hot water systems are solar-compatible. This means if there’s not enough sun to warm the water for everyone, natural gas will step in to provide as much hot water as needed.

If you’re considering a full solar set up at home, we think you should check all the costs carefully. There is potential for changes to distribution pricing or lines changes to impact solar users.

Short answer – no way! There is pressure on electricity supply at peak times with a shortfall in renewable energy to go around. In 2017 around 24% of gas produced in NZ was used to generate electricity to cover the shortfalls.

The increasing use of things like devices and electric vehicles can put even more demand on the grid. But every home that uses a gas appliance instead of electric is helping to ease that pressure. Just like many homes have a mix of electricity and gas, NZ’s energy mix has a balance of supply sources. It just makes sense.

The living is easy in a natural gas home. Providing comfort and convenience with fast, powerful hot water, home heating and cooking, natural gas is reliable, flowing 24/7. 


With increasing demand for electricity from things like multiple devices at home and electric vehicles, rest easy knowing that every appliance powered by natural gas is helping NZ out by easing pressure on limited renewable energy. 


Plus with The Gas Hub’s free connection offer, you’re onto a good thing by going with gas.

Let’s get out our crystal ball… What we do know is that for Kiwi homes and businesses, natural gas is here to stay for decades to come. Our electricity supply is reliant on it too.

However we aren’t sitting back and relaxing. We support NZ moving towards being carbon-neutral. There are technologies we are keeping an eye on that could see even lower carbon gas (biogas and hydrogen) being adopted in the future, as well as options for cogeneration.  

For now, natural gas still has an important role supporting NZ’s energy mix.

The future of gas

The conversation on climate change and decarbonisation has been heating up in New Zealand and around the world. Some are wondering if there is a future for gas in New Zealand. We say yes.

100% renewable energy is an aspirational goal. When you look at the big picture, we believe a balanced approach to our energy mix is needed. Natural gas still has an important role supporting New Zealand’s energy future.

Ultimately, we want Kiwis to feel confident in choosing gas for their home and confident they are contributing to a cleaner, greener New Zealand. Did you know that Kiwi homes connected to gas use only around 3.6% of all the natural gas produced and collectively contribute to less than 1% of New Zealand’s total greenhouse gas emissions?

Read on to see how gas in New Zealand is just getting started and how we think gas will energise our future.
