"Landowners could also consider the impact on public events, such as this weekend's Air New Zealand Hawke's Bay Marathon, where over 5000 people will be taking deep breaths outdoors on Saturday, with the effects of smoky air on the lungs of participants, their supporters and spectators, as well as the wider community."
Regional Council's climate and air quality scientist, Dr Kathleen Kozyniak, says the key is to make sure any permitted burn-off is only getting rid of dry wood, because dry wood produces a lot less smoke than wet and green material.
"We also recommend checking the weather before lighting up, for wind speed and direction, not burning on still winter mornings and being especially considerate of neighbours," Kozyniak says.
The regional council says materials which can never be burnt are treated timber or fibreboard, plastics, rubber products and tyres, batteries, materials containing bitumen, used or waste oil.
Other products include insulated electrical cables or coated wire, motor vehicle components, mechanical or electrical equipment, asbestos or radioactive material, and domestic or industrial rubbish.
