If you rely on bottled gas to heat and power your home, it’s essential that your supplier is reliable – delivering on time, every time.
Therefore it’s no surprise to discover that when it comes to the most important aspect of their bottled-gas supply, over a third (38%) of those in our survey cite great Customer Service as their No.1 concern.
Understandably, Value for Money is also an important driver of satisfaction for almost a third (27%) of respondents.
Here’s the full rundown of what the consumers in our survey say are the main things they consider when rating their bottled gas suppliers:
Bottled gas is either butane or propane gas that has been compressed into a liquid form and bottled. When release from its pressurised bottle, the liquid reverts to a gas, which can then be burned to fuel heating or cooking in the home.
While bottled and natural gas perform the same tasks: either used for heating or cooking in the home, there are differences between the two:
While there are over 2500kms of high-pressure supply pipelines in New Zealand, supplying gas to more than 60,000 customers, there is no mains supply in the South Island. And if your home isn’t already connected to mains gas, a new connection can be prohibitively expensive.
However because bottled gas is portable, it’s an easily accessible option if your home is off the mains gas grid.
Natural gas is often referred to as mains gas or piped gas, and is only available to homes on the mains network in certain parts of the North Island.
Unlike bottled gas, which is usually butane or propane, mains gas is primarily methane.

Homes using bottled gas usually have two 45kg bottles. When one empties, supply switches to the other and a replacement is ordered for the empty bottle.
How long a gas bottle lasts depends on your power usage, whether you’re using the gas for cooking, heating, hot water, or a combination of all three. Obviously, the more gas you use the more bottles you will have to purchase.
However, here’s a rough guide to gas bottle consumption for an average home:

Canstar Blue surveyed 5037 New Zealand consumers across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by PureProfile. The outcomes reported are the results from respondents who have a bottled gas account. In this case, 416 New Zealanders. Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criterion.
