While three V8 Supercars events remain before that time, Seven has elected to bench White immediately from its V8 Supercars coverage.
A V8 Supercars spokesman confirmed to Speedcafe.com that there are no short term plans to add a new member to the on-air team.
That leaves a reduced two-man commentary line-up of Crompton and Mark Skaife.
Pukekohe meanwhile sees Seven's Mark Beretta return to pitlane reporting duties alongside Riana Crehan following his absence from Symmons Plains and Winton while on the Tour De Cure charity cycling event.
It is expected, but yet to be confirmed, that White will return to the V8 Supercars fold under his new deal with Ten.
