The problem is that rail costs a lot of money to build and a lot of money to maintain. This is ok when you have a metro city of 5 or 10million+ but a city like Napier would never be able to afford to maintain it.
The economically way to build rail is for freight rail to be built because they pay for its use and it’s less of a burden on the government and then passenger rail forks off it.
Mostly for auckland I would like to see cycle expressways and better motorway and bus infrastructure. I’d also like to see them move driveways off the fucking main roads its dumb and causes so much traffic. Main popular roads should be footpath - bike - bus/t3 - car/ mirror
