A fraudulent sparky put lives at risk by continuing to do dangerous electrical work while under investigation.

The Electrical Workers Registration Board reached an interim decision this week to ban Pritesh Pritesh, also known as Pritesh Raicharan, from the electrical profession for five years after he wired an Eden Terrace unit so poorly an Auckland family faced the risk of electric shock or electrocution.

In July the Sunday-Star Times reported Pritesh was contracted to work in 2014 on a Housing New Zealand project to repair 5000 properties in Christchurch damaged by the earthquake.

SUPPLIED Pritesh attracted wild reviews on BuildersCrack.co.nz

​Pritesh was not a registered electrician but certified the work as safe with the aid of three pre-signed code of compliance booklets left in Christchurch by his then-boss Rakesh Kumaran.

Kumaran's former employee, Pritesh, left Christchurch and advertised himself as a registered electrician in Auckland until at least May this year.

JEREMY STEINBERG Fake electrician Pritesh Pritesh captured on CCTV entering an Eden Terrace property. Unable to register as an electrician for five years by the Electricity Workers Registration Board EWRB.

Mark Carter of TorqueIP, who inspected the electrical work at the Eden Terrace property, told the hearing there was a risk of electric shock to people in the building from Pritesh's wiring.

Rebecca Denmeade who appeared for MBIE, which bought the charges against Pritesh, said it was possible Pritesh had been wiring houses unsafely in Auckland for "quite some time".

Jeremy Steinberg, who owned the Eden Terrace property, reported Pritesh to MBIE after he charged him $60 for an "obviously fraudulent" Certificate of Compliance.

"That's when it all started to unravel."

Pritesh spelt the supposed supervisor's name wrong then forged the man's signature on the certificate he provided, Steinberg said.

"He just kept lying at every junction."

Steinberg said rave user reviews on trades website BuildersCrack.co.nz, which included a 4.5 out of 5 for workmanship, convinced him to hire Pritesh.

Steinberg was "p..... off" Pritesh continued to work and advertise while under investigation by MBIE.
