LPG pricing explained

How LPG is priced 

The price of LPG isn’t set in stone – it can move around depending on a few key things: international market prices, exchange rates, transport and delivery costs, and government regulations. Here’s a quick look at what goes into the cost:

How international prices determine what you pay

Even though some of our LPG is made right here in New Zealand, it’s still priced off an international benchmark called the Saudi Aramco Contract Price (Saudi CP), which changes every month. And since it’s priced in US dollars, the exchange rate also plays a part in what you end up paying.

The role of Government regulation

Some of the cost comes from regulatory schemes like the New Zealand Emissions Trading Scheme (NZ ETS). This puts a price on greenhouse gas emissions and means companies like us need to buy emissions units to cover our LPG usage. Those costs are included in the price you see.

Transport and logistics costs

Getting LPG from its source to your home takes a few steps. It travels from the source or port to our depots, then it’s trucked out to homes and businesses all over the country. Road user charges, shipping, storage, and the distance to your place all add up behind the scenes.

Understanding your Rockgas invoice

We keep things simple with two types of invoices:

Delivery-based invoices – Most customers will receive an invoice after each completed delivery. This includes your customer account number, invoice date, due date, and payment instructions.

Consolidated invoices – These are usually for businesses and are sent out on the 20th of each month. They include all completed orders up to the invoice date, with each order listed as a separate line.

If you’ve set up Direct Debit, the amount will be automatically taken on the due date. If not, just make sure your payment is in by the due date so you can keep your LPG flowing.

Invoices are due 20 days after the invoice date.
