"I think people will be really pleased when we do, they are great supporters of Rotorua and New Zealand mountain biking," said Mr Simpson.
"The official event HQ will be the Pig and Whistle Historic Pub, who've backed us since we set up the Society in late 2007."
For Gregg Brown from the Pig and Whistle it was an easy decision.
"We are well-stoked to be involved in such an awesome event, again," he said.
Mr Brown is chairman of the Rotorua Trails Trust, which will be the primary beneficiary of the championships.
"They do great work, in their own time, for all recreational users of the Whakarewarewa Forest," said Mr Simpson.
The society has donated $30,000 to a variety of causes since 2007, including the local trails.
When Rotorua hosted the championships in 2010 it attracted 1000 entries with Canada, Italy, Australian, South Africa and Ireland bidding for the 2011 championships. The finale of that was horizontal bungee, which Ireland won by the width of a beer can.
"It was great that South Africa went on to host in 2012," said society president, Gary Sullivan.
"Since then it's been in Italy, Japan, Alaska and Australia. Great venues, but lots of people still mention Rotorua as the best ever in 20 years of Singlespeed World Champs history. We have a bit to live up to."
"People started booking accommodation minutes after we announced the dates on our Facebook page," said Mr Sullivan.
"Apparently, we are really popular in South America. Who knew?"
Entries will open in the new year.
Mr Sullivan said they would be offering entry to riders from the 2010 champs first.
