Crankworx 2016 delivered about $8 million into the Rotorua economy - a $4.2 million increase on last year's event.
The mountain biking festival drew about 10,000 visitors to the city when it was held for the second time in Rotorua in March.
The main events took place at Skyline Rotorua Gravity Park on the slopes of Mt Ngongotaha and in the Whakarewarewa Forest.
An economic impact assessment of the 2016 event, produced by Rotorua's APR Consultants, will be presented to the Rotorua Lakes Council tomorrow during a meeting of the council's Operations and Monitoring Committee.
According to an agenda report the council committed to underwriting the event with $94,000 spent in 2015, dropping to $39,000 this year.
