Ruapehu was appointed as the lead agency in helping to identify regional tourism opportunities that now form part of the Accelerate25 Manawatu-Whanganui Economic Action Plan programme.
"An economic impact study has shown that successful implementation of the plan could increase the region's GDP by $66 million by 2025," said Mr Cameron.
Visit Ruapehu's general manager, Claire McKnight, said the district was increasingly becoming a year-round destination with virtually no off season.
She said tourism expenditure, measured through electronic card transactions, was still at its peak over the winter months. However, the warmer months were producing great results.
In 2015 spending during each quarter grew year-on-year. During the fourth quarter it was up by 16 per cent and it was continuing its upward trend at the beginning of this year.
"There's no doubt Ruapehu is benefiting from the great work Tourism New Zealand are doing offshore but ... the domestic market is providing much of our growth," said Ms McKnight.
"Ruapehu appeals to Kiwis. It's an outdoor destination just south of Lake Taupo, within easy reach of Auckland and Wellington, that has an abundance of family-friendly and also more challenging activities."
Meanwhile, Mr Cameron said the council had been trialling the placement of an official i-Site in the Department of Conservation Visitor Centre in Whakapapa Village, which was a New Zealand first.
"The success of this trial has seen the council commence discussions with the Army Museum in Waiouru about placing an i-Site inside the museum."
He said the council's investment in tourism infrastructure, such as the i-Sites and Visit Ruapehu, was key to growth in the district's tourism sector.
