His quote to build the house was off by nearly $250,000. And now Misi Sau Evile can't get his licence back for 10 years.

A bankrupt builder who underquoted for work on a south of Auckland home by nearly $250,000 has had his licence revoked and been banned from re-applying for one for 10 years.

Misi Sau Evile, previously a licensed carpenter, was disciplined by the Building Practitioners Board for carrying out building work in a negligent or incompetent manner, failing to provide a record of work, and bringing the licensed building practitioner (LBP) scheme into disrepute.

Evile misquoted the pricing and completion date of a complex two-story home on a semi-rural lifestyle block in South Auckland's Franklin district. He also only allocated six months to complete the work, and left the job for so long that nails rusted and the timber framing turned black, the board found.

The 10-year licence cancellation is the strongest penalty ever handed down by the Building Practitioners Board, the board said in a media release on Thursday.

The build commenced on September 30, 2016. The complainant had concerns about Evile's progress early on in the project.

Building Practitioners Registrar Paul Hobbs said the quote was based on Evile's standard pricing procedure, which the board considered negligent as it lacked the reasonably expected care in pricing, and illustrated a lack of knowledge and ability.

"The property owners provided evidence showing Mr Evile underquoted the job by almost $250,000 and only allocated six months to the build. Mr Evile also failed to provide a record of work, which is a legislative requirement under the Building Act."

The board found it was likely Evile simply agreed to the build for the amount of money the homeowners had available, rather than actual build costs.

"The property owners described the process as a 'start-stop' job, with Mr Evile leaving the job so long at points in the project that nails rusted and the timber framing begun turning black. They later found that during the build Mr Evile became bankrupt and was unable to complete the project," Hobbs said.

"There is no doubt that this behaviour posed a genuine risk to the public, which is why Mr Evile has had his licence revoked, and will not be able to apply for licensing for 10 years. He was also ordered to pay costs toward the inquiry."

"LBPs must follow their regulatory obligations and an aspect of that is clear planning, pricing and commitment to a project."

"Honesty and integrity is a key part of the LBP scheme and where there is evidence of this not being exercised, the board will discipline accordingly," Hobbs said.

To become licensed building practitioners are assessed as competent to carry out building work essential to the structure or weathertightness of residential buildings.
