Mr Shaw said once completed the track will host a national qualifying meet in February next year.
The following season, it was hoped it would host the central region BMX champs.
The ultimate goal was for the track to host the national champs.
Mr Shaw said the track would attract pro BMX riders to the region.
7000cu m, or 1200 truckloads, of surplus dirt will be used to build the new track, which will feature a starting gate that stands 5m high.
The extension of Guthrie Park is expected to cost up to $700,000.
The council is paying for the construction of the soccer fields and the $100,000 to $130,000 required to build the BMX track will be raised through community fundraising efforts.
The Hawke's Bay BMX club will lease the track from the council.
Mr Shaw said a quiz night held by the club in May had raised more than $6500.
The club was also selling tickets to a dinner fundraiser at the Thirsty Whale, Napier, arranged for August.
The club was interested in local businesses backing the track and online donations could be made to its Givealittle page.
Hastings District Council parks and property assets manager Colin Hosford said despite some inclement weather over the last month, the redevelopment of Romanes Reserve remains on track for completion in October.
"The playing fields are ready for grassing and this will be completed during the next dry spell.
"The contractors, Fulton Hogan are currently working on excavation and forming of the driveway and carpark.
"Council is pleased with the progress being made on this project, especially as the recent rain has had quite a severe impact on ground works."
