FAF RATE
FAF RATE: 16th - 22nd March 2026
12.0%
IMPORTANT NOTICE: MARKET VOLATILITY
With the recent rise in tensions in the Middle East there has been heightened instability in global oil markets, leading to sharp and unexpected fuel price increases. In response to this volatility we are moving to weekly FAF reviews, effective from 16 March 2026. We will return to our standard monthly reviews as soon as the fuel markets settle. Note: Our methodology for the calculation of FAF remains unchanged and continues to be based on the MBIE weekly diesel fuel data (see below).
FUEL ADJUSTMENT FACTOR (FAF) EXPLAINED
FAF is a variable rate used by the transport industry to manage fluctuations in the monthly cost of diesel fuel and the impact that has on operating costs. Fuel is a major cost component of our business and prices can change daily, resulting in significant variations over the course of time. FAF enables Normans to fairly and transparently manage these fluctuations on all customer accounts.
| MONTH | FAF RATE (%) |
|---|---|
| 1st to 15th Mar-26 | 10.4% |
| Feb-26 | 10.4% |
| Jan-26 | 11.2% |
| Dec-25 | 11.2% |
| Nov-25 | 10.4% |
WHAT IS FAF BASED ON?
FAF is based on the Ministry of Business and Enterprise’s (MBIE) weekly monitoring table click here. Using this information, Norman’s calculate the average of the ‘weekly national diesel discounted retail price’ for the last four weeks. Each time this average diesel cost increases by $0.05 above $1.249, the FAF rate rises by 0.8%.
For example, if last month’s national average is:
$1.32, the FAF rate will be 1.6%
$1.46, the FAF rate will be 4.0%
