This page provides a regional price comparison for main (reticulated) natural gas within NZ.
If your gas is bottled, here’s a use this bottled LPG price comparison instead.
For each region, I have charted yearly gas cost against gas used. Each gas supplier has a separate coloured line. The lowest coloured line represents the cheapest supplier.
In most regions, Energy Online is the clear price winner (note: Energy Online is now rebranded to Frank Energy).

Nathan’s Notes
Pricing and charts updated April 2019 from publicly available data. Charts should be treated as indicative only, so please obtain a firm quote from your retailer before signing up.
Contact Energy pricing is not included at present as I couldn’t find publicly available regional gas pricing.
I am only human, if you think I have made an error or something looks out of whack, drop me a line.
Interesting about Energy on line ,because Ihave just switched to Nova for gas on the recommendation of Whats my number.
Energy on line was not given a n mention .Trustpower was the second choice for gas and electricity.However Paua to the people and Nova were tops so that’s where Iwent.
Hi Claire. Do you know what your rates (daily and per unit) from Nova are? I wonder if they are offering ‘special’ rates via What’s My Number than they do otherwise.
I know some of the power companies used to do this (Energy Online in particular) in order to ‘game’ the rating table. I created this page after I was trying to find the cheapest gas provided for home, and the price comparison sites all said something different!
Hi Claire. Quick update, I have checked with Powerswitch and the Nova rates are out of date. They are updating them this week (10 April ’17). Cheers, Nathan
We changed from Nova to Trustpower 21 months ago and there was a significant price difference (saving) until recently, now I’m getting $500-$600 bills per month with less people in the house. The internet with trustpower is terrible, so have started my homework again, can’t wait to change suppliers in October.
Hi Nathan,
I have just been looking at rotorua prices. From what is available from my bill and online.
The following values were used.
Genesis: Daily 131.9c unit 9.95c
Nova Daily 110.635c unit 8.146c
Energy Online 123c unit 8.12c
This put Nova as the cheapest between 5000 to 20000 units by about $35 dollars on Energy online, with genesis being nearly $300 dollars per year more expensive.
regards Shaun
I need to get gas without electricity …
I came across your page after googling for average monthly gas consumption in Nz, and boy your monthly gas bill is a fraction of ours!
We just moved to Taranaki a month ago, have just received our first bill with Contact, and the gas charge is $276.25! We use piped gas for our hob and the infinity hot water system. There are two gas heaters installed and a couple of wall outlets where another gas heater can be connected, but we haven’t been using these at all. I chose Contact for their plan that charges only for the gas you use – so it has no fixed daily gas charge. Therefore this $276.25 is for the 1854kw of gas we’ve apparently used just on our showers and the few times I’ve turned on the gas hob to cook some pancakes or fry some bacon.
I’m dying on the inside because… I thought gas was cheaper than electricity. The electricity side of our bill is $93.56, and that’s with using the heatpump.
After seeing your breakdown of your monthly gas and power bill, I’m now wondering if we have a gas leak or something. That $276 for gas alone is more than our entire winter electricity-only power bills at our previous house!
