"It's erroneous to say we're developing only one small part of the park for mountain bikes," he said. "We are looking at developing a significant part."
Safety and managing "crossovers" of walking and biking tracks were among the issues and Mr Chambers said: "There are some constraints we have to deal with. The trust's primary concern is safety."
But the trust also has to clarify covenants which may affect use of "wheeled vehicles" within the park.
It has in the past had concerns about people taking "shovels and spades" up to the park and building their own biking tracks and people removing signs, which the trust had put in place. .
Mr Wilkins said mountain biking on Te Mata Peak could rank it alongside Rotorua and Queenstown as offering some of New Zealand best shared tracks and could boost the region's economy by over $10 million annually.
"Best practice is shared-use tracks and this is now common practice in recreational parks throughout the world," he said.
"Shared-use tracks that are well signed are also much safer to use and nothing is unexpected."
Mr Wilkins and friends Damon Harvey and Russell Nettlingham have gained support from the Hawke's Bay Mountain Bike Club and Bennelong Mountain Bike Club, which regards Te Mata Peak as its home playground.
Bennelong club spokesman Richard Mills said: "The Te Mata Peak Park Trust needs to embrace mountain biking, take down the no-riding signs and let the tracks be shared."
