Sumich said she had given the alarms to her father to install but did not check if the job had been done.
"It is unacceptable this landlord failed to meet her obligations," said national manager of tenancy compliance and investigation Steve Watson.
"Ms Sumich, and in fact every landlord in New Zealand, has a legal and moral obligation to comply with tenancy laws, which are designed to save lives."
"Landlords are running a business, and have a responsibility to ensure their property meets all requirements under the RTA. This includes installing smoke alarms, having insulation statements for new tenancy agreements and installing insulation by July 2019," Watson said.
