He urged drivers to pay attention to level crossing alarms and not to cross if they see a train coming.
National rail safety charity TrackSAFE NZ repeated his call for caution.
"Unfortunately if people continue to engage in the reckless and impatient behaviour that we have already seen this year, then it is only a matter of time before we potentially have another tragedy on the railway," charity foundation manager Megan Drayton said.
The figures showed almost two thirds of the near-collisions this year were in the South Island, with five on the line between Rolleston and Greymouth, and four on the line between Christchurch and Invercargill, she said.
Registration details of drivers who try to cross in front of trains would be passed on to police, she added.
In 2013 KiwiRail recorded 107 near collisions with vehicles at level crossings, compared to 154 in 2012.
Reefton dairy farmer Jane Sluys, 56, died on Saturday, nine days after her ute and a fully laden coal train collided at crossing near Inangahua east of Westport.
The investigation into that incident is ongoing and there is no suggestion that Ms Sluys was at fault.
