Auckland's being described as a bit of a shambles after transport issues this week.  

Auckland Transport says up to one-in-three train services will be cancelled every day, and some days will be worse than others.  

KiwiRail says it's because of heat that causes the steel in rail lines to move if the trains pass over them too quickly. 

Mayor Wayne Brown told Mike Hosking that KiwiRail, AT, and Auckland One Rail blame each other for issues.  

He says heads of the three agencies are meeting with him tomorrow and they'll get a good bollocking.
