The initial construction of Transmission Gully is being described as a 'dog’s breakfast' as the chipseal and drainage systems prove unable to cope with demand. 

Newstalk ZB revealed yesterday that NZTA is planning to re-surface and rebuild several kilometres of the road north of Porirua, likely meaning lane closures during the day and full closures at night. 

Infrastructure NZ CEO Nick Leggett told Mike Hosking the road was rushed and opened without all consents being satisfied. 

He says New Zealand is not that experienced in building big projects, as things keep getting switched on and switched off.
