New national speed records are likely once Masterton's $3 million drag strip - now under construction - is finished, says project manager Bob Wilton.
Earthworks began on Friday to smooth the way for the project, a drag strip purpose-built to international standards, just east of Hood Aerodrome where races have previously been held.
Mr Wilton, chairman of drags host Masterton Motorplex, said the new strip's quality tarseal "should not be underestimated" as a factor in the speed of the vehicles.
"There could be some new national records set. We should be able to get some really good times there."
Five years after planning began and the expiry of an agreement with Hood Aerodrome, Mr Wilton said he was glad to see the new site now crawling with earthmoving machinery belonging to main contractor Oldfields.
