Event director Tak Mutu said the trust funding would provide greater opportunities for the wider public to enjoy the event.
"The funding we've received from the Rotorua Trust will go specifically toward providing free public access to the events we have planned on the Lakefront to coincide with the mountain biking festival,' he said.
"For instance, we'll have a range of great bands on stage during the week. Plus, we're planning some fun activities for kids and families. The Trust money allows us to open these events up to locals and others in town for the event."
Rotorua Trust Chairman, Grahame Hall, said the Trust was pleased to provide funding to Crankworx Rotorua as it will have a major economic and reputational impact on the district.
"Crankworx is the largest event of this type ever seen in Australasia. It's a real coup that Rotorua has won the bid to host it. The economic injection into the region is expected to be upwards of $15 million.
"Additionally, the world will be watching us for five days and getting to see the amazing region we all know and love. The Trust has always been focused on helping make Rotorua a better place to live, work and play. Supporting this major international event aligns perfectly with our vision."
