A Rotorua business which uses geothermal energy to heat its water is the first in the country to receive a Qualmark environmental verification.
Alpin Motel owners Steve and Gillian Osbourne were awarded a Qualmark Enviro-silver logo for their green approach to business.
Mr Osbourne initiated a joint venture with Environment Bay of Plenty to tap into the vast energy store in the underground water of Rotorua's geothermal system.
For the past year the Osbournes have been developing a "down bore heat exchange", a system using geothermal energy from water in a shallow bore to sustainably heat the motel's water, rooms and plunge pools.
"What we've done is just good business practice," Mr Osbourne said. "It's a reflection of this that it is good for the environment at the same time."
