"Rotorua should feel immensely satisfied that its trails and facilities are held in such high esteem."
Mr Donaldson's address at the summit was on 'Rotorua - building a world-class MTB destination.'
"In my speech I reinforced the vital point about much of Rotorua's success coming down to genuine partnerships.
"I specifically referenced the hard work and cooperation of our local clubs and volunteers, and the support and collaboration of iwi, forest managers, biking operators, the visitor industry, our council and central government," he said.
"Those partnerships and the major international events we've delivered, combined with Rotorua's outstanding and unique natural environment, are part of a magic formula contributing to Rotorua's growing international mountain biking reputation."
Mr Donaldson's costs for attending the Australian Mountain Bike Summit were covered by the event's organisers.
