Checks to make before work starts
Electrical workers: the EWRB says to ask to see the worker's licence ID, check it hasn't expired and that the photo matches, and search the Electrical Workers Public Register by name or registration number.
Licensed Building Practitioners: LBPs are on a public register at lbp.govt.nz. They cover restricted building work, which MBIE describes as work on a home's primary structure, weathertightness and the design of fire safety systems in multi-unit homes.
Insurance and paperwork: MBIE says that if the work is likely to reach $30,000 including GST, or if you ask, the contractor must give you a disclosure statement before the contract is signed, covering their skills, qualifications, licensing status and any insurance or guarantees. Once any residential building work is finished, they must give you copies of any insurance policy for it.
Wiring for openers and gates
A new power point near the ceiling, or a new outlet at a gate, is fixed wiring. The Electrical Workers Registration Board says only registered and licensed electrical workers can carry out or supervise prescribed electrical work, and they must give you a Certificate of Compliance for fixed wiring.
That's why the job form asks whether there is a power point near the ceiling: the answer tells the door specialist whether the job has an electrical part before anyone arrives.
Who quotes and does the work
The Door Hero never quotes, fits or inspects a door. The door business that takes your job quotes it and does the work, so the door, the price and the timing are agreed between you and them.
