A partnership between Hawke's Bay orchardists and the Hawke's Bay Regional Council aims to reduce winter air pollution.
An online tool has been developed by HBRC to help orchardists know when the conditions are appropriate to light fires, after council was approached by the Hawke's Bay Fruit Growers Association.
Air Quality scientist Kathleen Kozyniak says it can be difficult for orchardists to make on the day decisions around burning.
"A few orchardists are trialling the tool through winter and will give us feedback as it needs to work for them."
HBRC's Air Plan prohibits burning below 10km an hour when it is considered too still for smoke to clear, but over 25km/h it becomes a fire risk.
