Julian Dean's chances of an eighth ride in cycling's premier tour were scuppered by a broken leg in March but he is back in training and still hopeful of competing in the Olympics.
He will ride the Tour of Poland next month, along with another Olympic hopeful Hayden Roulston, who was overlooked for a ride at the Tour de France by his strong Radioshack Nissan-Trek team.
Bauer was in good form, having helped Garmin-Barracuda to victory in the team's time trial at the Giro d'Italia and becoming the fifth Kiwi to win a stage on one of the three Grand Tours.
BikeNZ said selection for the Tour de France would play a significant role in who they selected for the road race at the London Olympics.
Henderson, who will ride his first Tour de France with Lotto-Belisol, now looks to have secured one of the two spots with the other one a choice from Dean, Roulston and Bauer.
