• 1

  New Zealand publishes fuel cost figures in New Zealand Dollar, revised periodically — enter the rate currently in force for your case in New Zealand rather than an older stored figure so the result matches the official calculation.

• 2

  A fuel cost result for New Zealand is only as current as the rate you typed in: when the figure matters, re-run it with a freshly confirmed New Zealand Dollar rate instead of one saved last month.

• 3

  For large New Zealand Dollar sums, compare the fuel cost output for New Zealand against a rough mental estimate first; if the two are far apart, re-check the rate and the amount before trusting either number for a decision or a commitment.

• Rates in New Zealand move — annually, or with each fiscal announcement — and a Fuel Cost result computed from last year's figure misleads budgets and quotes alike. Re-enter the current rate whenever the underlying number changes.

• A percentage entered as a whole number where a decimal is expected (15 versus 0.15) is off by ×100 — the most common single error in rate fields. Check which form the New Zealand Fuel Cost field expects before you type.
