The housing minister has ordered an investigation into an Auckland boarding house following news reports showing it in a dilapidated state.
Last year, the Government established a compliance unit to enforce tenancy law for vulnerable tenants in substandard housing.
Housing Minister Nick Smith said, based on reports, the boarding house on Great North Road in Grey Lynn was not up to standard.
Dr Smith said he was concerned the people living there were not in a position to take the landlord to the Tenancy Tribunal if needed.
"We also need to be practical that there are vulnerable people who will just move on and then leave these slum properties for someone else to then put up with the poor condition - that's the very reason we eestablished the compliance unit."
The unit could force the landlord to refund rent or pay a fine, Dr Smith said.
