"The court notes, however, that there is the possibility that there was a fainting from the heat of the water and/or arrhythmia from the enlarged heart. The court cannot be satisfied to the legal standard required that there is a clear cause of death," he said.
During last year's inquest Coroner Bain said the motel owner had followed best practice with the use of his hot pools and commended the council for its geothermal pool testing and monitoring regime.
He said in his decision he recommended that the Rotorua District Council consider making compulsory in its control of thermal pools that the signage clearly displays a warning that the users of pools should not bathe alone.
The council's compliance solutions manager Neven Hill said the council would change the signs as recommended.
"We actually have a bylaw review which closes soon so there may be other actions".
Submissions to the Geothermal Bylaw review close today.
"We will add the coroner's recommendation to the bylaws and see what else comes out of the consultation. The bylaw review isn't complete yet."
