A New Plymouth man has been fined $18,000 for posing as a registered electrician.
Tauke Whana was sentenced in the Rotorua District Court today.
In 2015 Whana told a family member he was a licensed electrician and could install wiring in a house the relation was building.
He did the complete electrical fit out and issued a certificate of compliance with a false registration number.
It was later discovered the work was faulty and potentially dangerous.
Registrar of the Electrical Workers Registration Board, which took the prosecution, said the case was a timely reminder to always use a licensed electrician.
Whana was also order to pay legal and court costs.
