Auckland Seaplanes is New Zealand's first air operator to become a carboNZero certified organisation.
The scenic flights business has been operating for three and a half years and its chief executive Chris Sattler said that with this country promoting itself as green and 100% Pure ''it was the right thing to do."
There was increased interest from tourists from some countries in green businesses, especially tourists from Europe.
Enviro-Mark Solutions has awarded the certification for the business which operates an eight-seater 1961 de Havilland Beaver seaplane and a seven- seater 1965 amphibious Beaver.
Sattler said he knew of only one other aviation business around the world that had achieved the certification, a seaplane operation in Canada.
