"We expect between 500 and 700 participants."
He said there had been huge interest on social media and the registrations so far reflected that.
"We are very pleased with the interest. Most are from Taupo and Rotorua, there's been a lot of interest from Rotorua."
Mr Rameka believed that was not just because of Taupo's central location, but because it was seen as a mecca for events like this.
His message for those still wanting to take part was to register early.
"There is huge interest already. We wouldn't want people to miss out."
He said by offering a 50 per cent subsidy for Tuwharetoa descendants, he hoped more people would be encouraged to participate.
It meant entry was much more affordable compared to other similar events, he said.
"This is all about healthy lifestyle for whanau and communities.
"We are really looking forward to hosting all of the visitors to Taupo for this unique inaugural event."
IronMaori will be held in five locations around New Zealand in 2017, including Hawke's Bay, Taranaki, Auckland, Wairarapa and now Taupo.
