Tenants Protection Agency (Auckland) coordinator Angela Maynard said they were very happy with Labour's proposed rental policies.
She said Labour's policy to abolish 'no cause' evictions will give security of tenure.
Maynard said National's policies that allowed landlords to evict tenants at any time has given landlords "the ultimate power and flexibility" for too long.
Housing Spokesman Phil Twyford said a Labour government would not make things worse for the property market.
The rental market was not working properly because of New Zealand's "archaic" rental policies.
Twyford said Labour's focus was skewed towards tenants because renters deserved better conditions.
"What we've aimed to do is modernise rental laws that currently make life a misery for half of New Zealand that rent."
Housing Minister Nick Smith said both tenants and landlords needed to be treated equally and "demonising either group does little good".
