Regional gas price comparison

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.

The charts show yearly gas cost against gas used.   Each gas supplier has a separate coloured line.  The lowest coloured line represents the cheapest supplier.

How to read the charts

To read the charts, find your annual consumption in units (kWh) along the bottom axis and the price for each supplier along the vertical axis.

Here’s an example of how to read each chart:

Updated 2025 charts

Most retailers have moved to individual address lookup for pricing, which makes pulling together a price comparison much more difficult.

As can be seen from the historical charts (kept below) for almost every region apart from Whanganui through to Taranaki the most expensive and least expensive gas providers don’t really change too much.

Therefore to save some time I have produced Auckland only – however if you are really keen on me doing a chart for your area, get in touch and will pull something together.

2025 updated chart:

Important – Check how many units you are using per year, as this alters which provider is cheapest. This will provide the most accurate comparison result.

For info – That Power Guy used to have gas water heating (only) which for a four person household was around 7,000 units per year (low user). It wouldn’t take much more consumption (large family, gas heating or cooking) to push above the 10,000 units p.a. range.

Up to 10,000 units p.a. – my pick is Genesis Energy – Standard User for piped gas

It’s quite close at the lower consumption levels, but Genesis Energy is consistently cheap for a range of lower consumption levels which gives them an edge in my opinion.

Above 10,000 units p.a. – cheapest is Contact Energy for piped gas.

As consumption increases, Contact’s pricing clearly beats the competition.

==== Historical charts (out of date) ====

I have kept these here for posterity only, they are out of date – but a useful reference for how gas prices can change by area.
