On March 2, once the votes are tallied, Bike Wise will announce the winner.
Rotorua Lakes Council Sport & Recreation Strategy portfolio leader, councillor Charles Sturt, said the Whakarewarewa Forest was home to one of the oldest mountain bike networks in the country.
"The Redwoods area is very popular throughout the year. With over 140km of trails there is something for riders of all abilities - from beginners and young families to experts looking for thrills and spills."
Destination Rotorua Marketing general manager Oscar Nathan said Rotorua had become the mountain biking Mecca of New Zealand.
"We've got single-track trails that have been voted as some of the best in the world. You only have to see the number of people heading into the Redwoods every weekend to see how much of a driver for visitors the trail network here is.
"Our research tells us that Kiwis are drawn by natural attractions and activities like our lakes, forests, geothermal pools and mountain bike trails. So it's good to see that word is getting out there about the fantastic mountain biking we have in Rotorua."
