The results of decades of under-investment in Auckland infrastructure are becoming clear.

Auckland Mayor Wayne Brown's demanding Auckland Transport stop all projects that were funded by the Regional Fuel Tax. 

The tax is being scrapped late June, and the mayor says it'll leave a $1.2-billion gap in transport funding over four years. 

Trains were also cancelled this week due to heat speed restrictions on the tracks. 

Committee for Auckland director Mark Thomas told Mike Hosking that their report found transport is almost the number one priority for the city. 

He says they'll be arguing for much quicker and a larger solution to Auckland's problems, because it seems to be getting worse week by week.
