Although the RTA says tenants must pay for water, getting them to actually do that is another question.
Watercare Services, which supplies water to Auckland, has a clause in its supply contract that says it can pursue landlords if tenants don't pay. That's because the water supplier defines "customers" as the owner of the property.
David Whitburn, president of the Auckland Property Investors Association, says his organisation is lobbying Watercare Services to change its approach. "We firmly believe that water should not be treated any differently to any other utility such as electricity or telephone services, where the supplier's contract is directly with the tenants who use the services and not the landlords who own the premises."
Whitburn says Watercare's policy regarding bill payment results in increased administration time for landlords to collect payments for metered water and being left with unpaid bills at the end of tenancies.
"Watercare's policy is to bill the property owner as soon as the consumer's water bill becomes overdue. For owner-occupied dwellings, (which is) the majority of properties, Watercare's policy is great. But for rental properties this is a major time sink for landlords and property managers in re-invoicing and chasing up water accounts.
"We just wish water bills were treated the same as power bills," adds Whitburn. "Our lobbying efforts get blocked by deferrals and local government blaming central government, who in turn blame local government. A change of legislation seems necessary."
This story has been corrected from a previous version, which failed to say that landlords must still pay the wastewater charges where the water supply is a tank supply.
