The lower South Island is the worst part of New Zealand for level crossing accidents, according to Ontrack.
On Sunday, the lines company issued a study which concludes almost 40% of level crossing collisions over the past five years were in, or south of, Christchurch.
Throughout New Zealand, there were 149 collisions at 1398 crossings over the five years. Some 15% of the collisions occurred south of Dunedin.
Ontrack chief executive William Peet says the worst collision statistics are in the Selwyn district immediately south of Christchurch, with eight collisions over the five years studied.
Invercargill City and Clutha district, along with Christchurch City, recorded seven collisions over the past five years.
