Ms Liu made a complaint to the Real Estate Agents Authority and their complaints committee found agents Hanok Shin and Philip Davis were guilty of unsatisfactory conduct.
The committee found the advertisement was ``completely misleading'' because it was hard to believe anyone would find an apartment with limited occupation ``satisfactory, let alone great''.
It decided each agent should pay a fine of $6000 and their agency $5000 however, all three parties appealed against the size of the penalty.
Auckland property lawyer David Kirkpatrick was called as an expert witness and said he could find no evidence on the Auckland Council file that the limited occupation right had been imposed as part of the resource consent.
He concluded there was no lawful restriction which could impose a limitation on Ms Liu's right to occupy the apartment fulltime.
The tribunal also heard Barfoot & Thompson's intranet system was not particularly reliable at the time of the sale.
The tribunal said it was not certain about the legal status of the accommodation restriction and in the circumstances the fines were too big.
It ordered revised fines of $1000 for each agent and $3500 for Barfoot & Thompson.
