An NZTA spokesperson advised motorists to expect delays heading into Waipawa on State Highway 2 while crews battled the fires.
Four fire crews, four tankers and a helicopter were fighting the blaze at 1pm.
It was not threatening any structures or buildings, the spokesperson said.
Areas now in a restricted fire season run from just south of Wairoa to the Tararua District.
These areas are Esk-Tutaekuri, to the north and east of Napier; Ahuriri-Heretaunga, which encompasses both Napier and Hastings cities; Tukituki West and Tukituki East, which run along the Ruahine Ranges and encompass Waipawa and Waipukurau; and the southern Hawke’s Bay coast, which runs from Haumoana south to Pōrangahau, which is also a restricted fire area.
Hawke’s Bay community risk manager Nigel Hall said the area was experiencing warm, windy weather, with little rainfall expected over the next month.
“Last month alone, we saw 37 vegetation fires across the Hawke’s Bay District escaping from old burn piles, driven by wind.
“The slightest spark in windy, hot conditions can cause a fire that will spread very quickly in areas that are already extremely dry for this time of year.”
Hall said anyone who had burned vegetation at any time in the past few months should check that the fire is completely extinguished.
“Spread it out and extinguish completely with water,” he said.
“We expect anyone planning on lighting a fire to have a permit if they are in the restricted fire zone.”
MetService meteorologist John Law said the dry conditions and high temperatures Hawke’s Bay had been enjoying could turn dangerous if there’s any breeze at all.
“In terms of our rain totals, it’s been dry and will stay pretty dry, at least for the rest of this week.
“Those are all conditions that can make wildfires really dangerous.”
