Auckland Council's manager of regulatory compliance Steve Pearce said the sentence reinforced the importance of complying with district plan rules.
"The ongoing effects of building without resource consent on sites of ecological significance can be significant, and may adversely affect the ecosystem and other environmental outcomes," he said.
"Generally speaking, we take a graduated approach to enforcement and will help people to comply where we can, such as by allowing time for people to make issues compliant or giving them the opportunity to apply for any consents and permits that might be necessary."
However, he said, if offences cause significant effects, or the offenders continue to ignore their requirements, the council will take enforcement action, including through the courts.
Pearce said Gilinsky's case served as a reminder to those wanting to build to consult with the council prior to commencing any building work, to ascertain if a consent is required.
"Anyone who wants to find out if their project requires a consent can visit an Auckland Council service centre to speak with a planner, or phone the council on 09 301 0101."
