Advocates for tenants want the government to give renters long-term protection during the Covid-19 crisis.
Several community organisations said tenants should not have to pay more than 30 percent of their income on rent.
They also wanted all emergency housing grants to be non-recoverable, and for boarders and flatmates to have tenancy rights.
The government has already brought in a six-month freeze on rent increases and restrictions on landlords terminating tenancies.
Ben Schmidt of the Manawatū Tenants' Union said more needed to be done.
"Changes that have passed are not there to protect tenants in the longer term yet," Schmidt said.
"We need to make it longer term than just the next six months because the right to stable and secure housing should not just be a short-term fix."
