Rockgas will be introducing a temporary, variable price adjustment called a “global disruption adjustment”, which reflects increased LPG and diesel costs due to the conflict in the Middle East. For the majority of customers, including residential households, the adjustment will apply from 3 June 2026 and will be removed once costs return to pre-conflict level.

We want to reassure you that there are no current LPG supply issues. Rockgas has access to both local and international LPG, and we’re continuing to supply all of our customers across the country as normal. Rockgas has been supplying customers for over 90 years, and our supply chain is well established.

The Conflict in the Middle East is affecting our global supply chains, which has increased the cost of buying LPG and diesel.

From June 2026, we’re introducing a temporary variable adjustment called the ‘global disruption adjustment’ which reflects increased LPG and diesel costs.

We’ve kept this adjustment separate from our standard LPG pricing so it’s clearly visible on your invoice.  It will be reviewed monthly, can move up or down as costs change, and will be removed once costs return to pre-conflict levels.

To help you stay up to date with the latest rates for the global disruption adjustment, we’ve put together the table below. The April costs have been used as an example only, these will be not be applied to any LPG invoicing.

As a result of the conflict in the Middle East, the cost of buying LPG and delivery-related costs like diesel and AdBlue have gone up.

Within three working days of the start of each month, we will update our website with any changes to the global disruption adjustment. Any changes will be to reflect movements in both the LPG and diesel/AdBlue costs above pre-conflict levels.

The variable adjustment will appear on your invoice as a separate line called global disruption adjustment.

No. When LPG and diesel costs stabilise and return to levels prior to the conflict in the Middle East, we will remove the variable adjustment.

The removal of the increase will take place from the first working day of the month after costs have come down to the pre-conflict levels.

Cost increases attributable to LPG and diesel/AdBlue are tracked monthly. These costs are compared against reference prices which have been set per market rates directly prior to the conflict occurring.

No, the global disruption adjustment does not relate to rental charges and other fees such as after hours charge.

What you pay is made up of three components:

1. Your current LPG cylinder or metered LPG price excluding GST (the ‘base rate’)

2. A percentage for the global fuel disruption adjustment (the ‘GFDA’)

3. A percentage for the contractual global LPG disruption adjustment (the ‘CGLDA’)

We start with your base rate, then add the two percentages (point 2 and 3 above) together to get one amount. This is then used to calculate the variable adjustment of your total invoice.

1. Start with the LPG cylinder/metered LPG price (excluding GST), i.e. the base rate

2. Add the two percentages (GFDA + CGLDA) to get the variable adjustment percentage rate

3. Work out the variable price: base price × total variable adjustment percentage rate

4. Add the variable adjustment to your cylinder/metered LPG price to get your LPG subtotal (excluding GST)

5. Add GST to get the final amount you will pay

You can calculate the variable adjustment you will pay according to the following formula:

Base rate + (Base rate x (GFDA%+ CGLDA%) )= New rate (excl GST) + GST = Total rate

A worked example of this is: $135.30 + ($135.30 x (1% + 2.1%) =$139.49 + GST = $160.41

In this example, $135.30 is the base rate, 1% is the GFDA and 2.1% is the CGLDA.

Disclaimer: please note that this calculation is provided for illustrative purposes only and is not intended to be relied upon as a final or binding calculation. It is subject to change and may differ based on the base rate, the GFDA and the CGLDA, and applicable contractual terms.

We know any price adjustment is unwelcome so if you don’t accept the temporary adjustment, your options are set out in the terms that apply to you. This may be your individual contract with us and/or our general terms and conditions available on our website. Those terms and conditions will explain if you can cancel your account, and how much notice you need to give us.

For example, if you have bottles delivered to your residential home, you may end your agreement at any time, including before the price adjustment change takes effect, in accordance with the Rockgas bottled LPG – Feel the Energy Terms & Conditions on our website by sending us an email to LPGenquiries@rockgas.co.nz.
