He said the company had been working out of the Mount for 30 years and had never been issued an abatement notice before.
The odour was a product of "smoke". He said it was only bad on that particular day and it had not been an issue before or since.
The company emitted water vapour from the plant daily, but this did not cause any problems for the surrounding environment, Palmer said.
Mellor said the public was quick to notify the regional council of the odour and it identifiedthe source within 30 minutes of the first call.
He said the operation quickly ceased and the odour improved.
It was the first enforcement action the council had taken against Allied Asphalt Limited, he said.
Across the road, Allied Automotives owner Brayden Pritchard, said smoke and odour often billowed into his workshop from businesses in the Mount industrial area.
He said on that particular day, smoke was pluming from Allied Asphalt and it could be seen going all the way to Matakana.
"You don't want something like that in central Mount Maunganui."
Pritchard said he was considering moving away, partly because of the constant odour from surrounding businesses.
