Peter Calnan is an auto electrician but he's not a qualified electrician so when he carried out electrical work at a Riri St property leaving live cables hanging from the ceiling he broke the law.
As a result he's been prosecuted by the Electrical Workers' Registration Board and fined more than $2000 in the Rotorua District Court.
Calnan, of Rotorua, initially appeared before Judge Maree MacKenzie on a charge of failing to minimise the risk of injury to persons or damage to property.
He's subsequently pleaded guilty and been convicted and fined $2100 by Judge Louis Bidois who also ordered him to pay court costs of $130 and solicitor's fees of $226.
According to a Summary of Facts released by the court Calnan carried out electrical work at commercial premises he owns and leases in Riri St between June 1 and July 9 last year.
That was after the property had been reinstated following a fire which gutted it in 2013.
