The most expensive flight, when Hawke's Bay Today checked at 9.30am on Wednesday morning, was $197, from Hawke's Bay to Auckland, on Saturday, July 6, at 6.15am.
A spokesperson for Air New Zealand said the biggest fare reductions related to their lowest fares, but more expensive flights had also seen a reduction.
"Naturally, as the cheapest fare class, lead-in fares tend to sell first and we always recommend customers book early in order to secure the best possible deals."
They said flight prices would still vary on any given day, as they had before the price drop.
Prior to the announcement being made, Regional Economic Development Minister Shane Jones said he hoped commuters would be able to fly cheaply as well.
"There's no point having a very cheap fare at 11.30am or 13.30pm in the middle of the day and the fares continue to be horrendously large when most enterprises and people need to travel," Jones told the New Zealand Herald on Tuesday.
"It's no good having a cheap fare for Nana to visit the whānau whilst the day-to-day business [people] are choking with excessively high airfares."
"I want to be sure that it improves the productivity and the affordability of people who have to go in and out of the provinces very early in the morning and in the evening."
Hawke's Bay Today has approached Jones for further comment.
