"Vegetation is tinder dry and even the smallest spark could ignite a fire," Mr Yeates said.
"We ask that farmers and the general public be extra vigilant and report any smoke sightings to emergency services on 111."
During a prohibited fire season, it is an offence for any person to light a fire anywhere in the district or to cause or assist any person to light a fire.
This includes braziers, incinerators, charcoal barbecues, bonfires, Chinese lanterns, pizza ovens and burn-offs.
"A scrub fire at Matata and a grass fire at Julians Berry Farm last week were quickly extinguished by the fire service," Mr Yeates said.
"Fortunately, on both occasions there was very little wind to fan the fire, otherwise we may have been dealing with something major."
He said with no significant rainfall in sight a total fire ban would remain in place until further notice.
