But he urged all motorists to adhere to the road rules and be alert to potential hazards.
"The Waikato road network is for the use of everyone and there is clearly sufficient room for all modes of transport if consideration is given,'' he said.
"Intersection rules are there to prevent crashes such as this from occurring if road users adhere to them. Sometimes motorists can become too complacent and believe because they have good local knowledge they will be OK.
"What police are saying, however, is that it is important that you maintain your situational awareness and be alert of who you are sharing the road with and potential hazards.''
The five schoolgirl cyclists injured in the collision are now at home recovering.
The teenagers from Waikato Diocesan School for Girls were out with their coach training for the upcoming North Island Secondary School Champs.
Three of the girls were flown by the Westpac Rescue Helicopter to Waikato Hospital with serious injuries while the remaining two and their coach Pip Sutton were taken via ambulance.
Ms Sutton, a Waikato University student who broke her wrist in the accident, did not want to talk about the crash.
The Hamilton school's website said the parents of the girls, all aged 17, rushed to the hospital last night. The girls were later all discharged from the emergency department.
It could be up to two weeks before police decide whether charges will be laid against the van driver.
Waikato Highway Police Sergeant John Stapleford said police had interviewed the driver, a Hamilton man on his way home from work, but were yet to interview the teenagers.
