Rotorua's Millennium Hotel has retained its Enviro Award Gold status as well as its 4 Star Plus hotel rating from Qualmark.
A founding member of the Rotorua Sustainable Tourism Charter, over the past 12 years the hotel has been continually working towards best practice, as more and more travellers make accommodation decisions based on eco-friendly operations.
General manager Pipiana Whiston acknowledged it had been a team effort.
"I am delighted that all our staff made a contribution to our continued environmental commitment which has secured our Enviro Award Gold rating for a third time. Millennium Hotel Rotorua has had many green initiatives in place which have become second nature in our day to day operations," she said.
Ms Whiston said constant monitoring ensured the hotel would become more environmentally efficient and sustainable.
