Wong was sentenced at the Auckland District Court last week.
Judge David Kirkpatrick said Wong was an experienced developer, so there was no explanation for why he did not follow the rules. He said the offending called for a substantial penalty.
"In particular, the purposes of the Building Act include providing for the safety of occupants of buildings. The deliberate behaviour of the defendant in failing to obtain the necessary consents and in failing to have the specified systems checked and approved requires a deterrent sentence."
Mayor Phil Goff said the penalty reflected the serious nature of the offending and would send a strong message to anyone purposefully not meeting their obligations under the Building Act.
"Those who flout the rules in such a manner need to know that they will be caught and face the consequences of their actions."
Auckland Council compliance response and investigations manager Kerri Fergusson said the offending in this case was calculated and deliberate, for commercial gain, and put occupants and neighbours at risk.
She said the sentence should act as a deterrent to others wanting to avoid the legal process of obtaining the required consents and inspections.
