Bay City Rental had also previously been before the tribunal for non-lodgement of bond.
"There is no justification for this behaviour, and particularly with their previous experience at the Tenancy Tribunal, the company should have known better.''
''The fact that TCIT (the ministry's tenancy compliance and investigations team) had discovered 126 breaches of the RTA shows a massive failing in the company's business operations and lack of understanding of their obligations."
The lodgement of bonds is fundamental to the integrity of the tenancy system, he said.
On 73 instances, Bay City Rentals failed to lodge the bond paid by the tenant within 23 working days to the Tenancy Bond Centre.
The delay in lodging bonds ranged from 31 to 701 working days, with an average of 266 working days.
The tribunal awarded 73 orders of exemplary damages of $150 where the landlord failed to lodge bonds within the legislative timeframe.
A further 53 orders required Bay City Rentals to pay $75 where no insulation statement was provided to the tenant as part of their tenancy agreement.
In many cases the tenancy agreement recorded that insulation would be assess later. In other cases the statement referred to there being compliant insulation but did not specify the type or condition to demonstrate it was sufficient to keep the property warm and dry.
"Compliant insulation statements gives tenants reassurance in knowing the state of the insulation in their rental home when they start a tenancy," Watson said in the statement.
"These orders serve as a timely reminder of the upcoming Healthy Home Standards which will require landlords to ensure they meet all required standards and provide a compliance statement with every new, varied or renewed tenancy from 1 July 2020."
The tenancy compliance and investigations team was established following the changes to the RTA that came into effect on July 1, 2016. The team focuses on significant or ongoing breaches of the RTA which pose a significant risk to vulnerable tenants.
