Size bottle – We supply 9kg 12kg, 15kg, 19kg and 45kg bottles. Delivery conditions apply for the customer-owned 9kg bottles which work on a swap basis.

Most people just rent the bottles, as we are then responsible for maintaining and delivering them. It’s much easier, and much safer all round!

If bottles are lost or stolen ring us and let us know immediately. You are responsible for the cost of the cylinders but insurance should cover this cost.

Give us a ring on 0800 LPG 2 YOU and we’ll soon tell you. It’s best to call us and find out!

Yes – to start with at least! We do prefer dogs to be restrained during our visits. Over time, the dogs and the drivers get to know each other, and at that point we are happy for your pooch to be roaming free when we arrive. Please let us know you have a dog beforehand if it’s a first-time delivery, just so our drivers don’t get surprised!

Yes – as long as our drivers are safely able to do so, it won’t be a problem. There are certain legal requirements we have to abide by, however we will explain these to you if you have any concerns. If you are away from your property at the time of delivery, our team will email you should they run into difficulty – otherwise they’ll go right ahead and deliver your gas as normal.

Yes, our cylinders are perfectly safe, and are designed to withstand incredible amounts of pressure and heat. Even during the most intense fires, our cylinders will not explode – they will simply release small bursts of gas in a controlled manner to reduce their pressure. All of our bottles are regularly maintained and tested, and we even go the extra mile by leak-testing your connections at every delivery. Safety comes first here at Rockgas Wanganui! 

Yes. While smelling an odour of LPG may not in itself be a sign of danger (there can be several reasons for this) it’s always best err on the side of caution and to call us or a registered gas fitter.

Yes. They are designed for this, as we all know how strong the NZ sun can be! Don’t worry if your cylinder is in direct sunlight, these bottles are built and maintained right here in NZ, for our specific conditions.

As long as the bottles are stored upright in a well ventilated area they will be fine for several years, so if you’re ordering gas for your bach or holiday home, it’s perfectly fine to use small amounts over a number of years!

No, unfortunately we do not deliver during statutory holidays.
