A property investors' group says it hopes the Wellington Tenancy Tribunal makes the right decision and evicts families of Mongrel Mob members from their homes in Lower Hutt.
A tribunal adjudicator on Friday reserved a decision on whether the families in state houses in Farmer Crescent should be evicted.
Housing New Zealand in March gave five households 90 days to leave after a spate of incidents of gang intimidation which forced a woman and her children out of their home.
Two of the houses have been vacated, but three other families are digging in their heels.
New Zealand Property Investors' Federation president Martin Evans says both private and state landlords need to be able to protect the rights of their tenants and neighbours from the harmful actions of other tenants.
The tenant's lawyer Robert Lithgow, QC, told the tribunal on Friday the termination notices were unlawful under the Bill of Rights Act.
