Fire and Emergency New Zealand said the grass fire on Carrick Rd, near the Ngaruroro River trail, burned 30 metres by 20 metres.
A Fire and Emergency New Zealand spokeswoman said a truck was on fire in the grass when crews arrived, but it was yet to be determined whether it caused the fire.
Three fire engines and two tankers from Hastings put out the fires in two hours and four minutes.
Police said they will be making inquiries into the fires, although there is no confirmation they are suspicious, a spokeswoman said.
