Housing Minister Nick Smith announced plans  to strengthen residential tenancy laws, including requirements for landlords to provide smoke alarms and insulation. We will tell you the important two things in this blog today.


1.All rental properties must be insulated by July 2019, though exemptions apply to properties where it is physically impractical to retrofit insulation.

What are the Insulation standards?

  • Ceiling insulation (minimum thickness of 70 mm) must cover all applicable habitable spaces (i.e. spaces used for daily activities), excluding spaces required around downlights and flues (another property immediately above counts as ceiling insulation)
  • A suspected subfloor must have underfloor insulation in reasonable condition, covering all applicable habitable spaces (a concrete slab counts as underfloor insulation, as does a garage or another property immediately above).

We checked to insulation companies if we will need to insulate to walls as well, however it is not necessary so far. This is a big good point for all of owners.

2.Smoke alarms must be installed in all rentals from July 2016, but tenants will be responsible for replacing batteries and notifying landlords of defects.

What are the Smoke alarm standards?

  • The new smoke alarm standards required a minimum of one working smoke alarm in a hall or similar area, within 3m of each bedroom door.
  • In self-contained sleep-outs or caravans, at least one working smoke alarm would be needed, in line with Fire Service recommendations.


180,000 New Zealand homes required insulation and 120,000 homes needed smoke alarms. The Government said the average cost of retrofitting both ceiling and floor insulation was about $3300.

Landlords could apply for a subsidy through the “Warm up New Zealand: Healthy Homes” scheme, but funding for that programme was only guaranteed to run till next June.


What is the criteria for government funded insulation?

  • Home built before 1st January 2000
  • Have a valid Community Services Card
  • Own your own home or rent privately (NOT a housing New Zealand home)
  • Have someone over 65 or under 17 living in the home


The Cabinet paper showed properties sold and immediately rented back to the former owner-occupier for up to 12 months would be exempt from the new laws.

Properties a landlord intended demolishing or substantially rebuilding within 12 months of a tenancy starting could also be exempt, as long as landlords provided evidence of relevant resource or building consent.

They recommend to owners to do this earlier, not later, as there may be issues with sourcing enough insulation or labour later.

Born in Japan in 1973. At University I learned Japanese History.

After graduation, I worked at a major Dental material company as a top salesman. In 2002 I firstly set my foot on land in New Zealand, and have started to engage in NZ Construction firm since 2004. From the 8 years' experiences at construction sites and sales experiences in Japan, I devote myself to satisfy customers from consultation to construction and after care services.

Within the first 4 years after the foundation, half of Japan Homes' customers were similar ages of mine. So that their life environment such as a number of children were also similar to mine therefore I was able to understand the customers' situations and wants more. Meanwhile there are also many customers of my father's generation, which is always appreciated because I can learn lots of good things from them.

We try our best to provide services that you satisfy, such as schedule, quality and after care service.

"I can trust you with any projects." "You are the man who I can rely on when I am in trouble." I enjoy working to get these words more times and to create as more smiles as possible.
