Fuel Adjustment Factors

The Variable Fuel Factor (VFF) is a charge that is applied to Domestic Courier Services to off-set the current fuel volatility. The total price you pay for a courier product/service will comprise of two components – the base price and the variable fuel factor. Multiplying the base price by the variable fuel factor will give the total price.

From Monday 30 March 2026, in response to ongoing global conflict and fuel price movement, the VFF will be set with reference to fuel prices from the previous 2 weeks, with a 1-week lag.

For example: VFF effective 30 March is based on the average of fuel rates for weeks ending 15 March and 22 March.

This methodology will remain in effect until further notice.

We have previously used fuel price monitoring data published by The Ministry of Business, Innovation and Employment (MBIE) as our index; however, MBIE has temporarily ceased publication due to volatility in the global market. Accordingly, we will utilise pricing data supplied by BP, our principal fuel supplier, as a representative market-based index for this interim period.

This methodology will be reviewed on a weekly basis, with adjustments made where appropriate in response to fuel price movements.

Post Haste Group reserves the right to update the methodology or index used where required.

The VFF will be calculated on the first day of each month and will be based on the average diesel price (adjusted for regional fuel taxes) from two months earlier. By using this mechanism, we can:

• Provide transparency for customers to see how it is calculated
• Take into account any shifts in the price of fuel that impact significantly on the price of moving courier items

We at Post Haste recognise the increased cost of fuel (VFF) is adding to your business and that the increased price of diesel is growing at a higher rate than previously experienced.

Accordingly we have revised our mechanism. Instead of a 0.1% increase for every additional $0.01 in the average pump price*, we have slowed the rate to 0.1% for every $0.02 increase.

We have published a revised table. As we don’t anticipate fuel dropping below $1.45 we have used this as the new trigger point (from $0.95 historically) and fuel will increase/decrease at the slower rate, from this base.

*Average diesel price (adjusted for regional fuel taxes) as published by the Ministry of Business, Innovation and Employment (MBIE) – we will calculate the VFF for any given month using the average diesel prices from two months earlier.

A current diesel rate of $1.89 under the historical pricing mechanism meant a VFF rate of 9.7%. Under the revised mechanism, the rate is 7.4%.

VFF will be rounded up to the nearest cent; this is updated monthly and will be automatically adjusted on your invoice.

The rates for our Variable Fuel Factor will be recalculated on a monthly basis.

Our website will be updated each month detailing the increase/decrease for that month.

The New Zealand Emissions Trading Scheme (ETS) is part of the Government’s primary response to global climate change. Effective 1st July 2010 an additional tax will be applied to fuel, and passed on through the pump price. For more information on the ETS visit www.mfe.govt.nz/ets.
