"These forged documents could have had serious, detrimental effects on New Zealanders' health and safety," Hobbs said.
"We have not taken his offences lightly, and in turn, Feng will not be able to practise as an LBP."
Producer statements also relate to professional indemnity insurance cover. By forging these Feng was jeopardising potential insurance cover and compliance assurance for consumers and councils.
Feng was convicted in the Auckland District Court of an offence punishable by imprisonment for six months or more, which reflects adversely on his fitness to carry out design work; and to have acted in a manner that would bring the LBP regime into disrepute.
"The bottom line is that Feng's misconduct has brought the LBP scheme into disrepute," Hobbs said.
"Fraudulent behaviour in any shape or form will not be tolerated, which is why Feng is no longer an LBP.
"New Zealanders can have confidence that when the board is made aware of LBPs who are breaching the law, and not upholding the responsibility that comes with being an LBP to the public, we will ensure they are disciplined."
Feng was also ordered to pay $1000 toward the costs of the board's inquiry.
