The Government is considering changing tenancy law to support the growing number of people renting indefinitely.
Some tenants say lease and notice periods provide very little stability for renters wanting to put down roots.
Building and Housing Minister Nick Smith said officials were reviewing the standard tenancy contract set out in the Residential Tenancies Act.
"We're interested in improvements that we can make in the residential tenancy law to try and provide a greater degree of security and to make it better for those that are renting."
Dr Smith said he was hoping to propose changes at the end of this month, and introduce legislation to Parliament by the end of the year.
Labour's housing spokesman Phil Twyford said any reform should also include minimum insulation standards for rental properties.
