Domestic Variable Fuel Factor FAQ

What is a Variable Fuel Factor (VFF)?

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.

How much will the VFF cost me?

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

On the 27th August 2018 the retail price of fuel as published by the Ministry of Business, Innovation and Employment was adjusted by $0.32 to account for the Auckland Regional Fuel Tax. (Auckland Council implemented a $0.10/litre [excl GST] regional Fuel Tax on July 1 2018)

How will this impact my business?

We will be using a base rate of $0.95 (diesel pump price including GST) for domestic courier services.

Every 1c movement above $0.95, in the average pump price*, will result in a 0.1% increase in our pricing. 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.

Nationally and globally, the courier and transportation markets have seen massive increases in fuel prices. In the past, Post Haste Couriers has tried hard to absorb these costs, minimising the impact on our customers. Unfortunately prices have come to a level where we must follow other transport operators in implementing a "fuel surcharge" system. If road user charges continue to increase we may look to incorporate this into our VFF methodology at a future date.

*Average diesel price (adjusted for regional fuel taxes) as published by the Ministry of Economic Development - we will calculate the VFF for any given month using the average diesel prices from two months earlier.
