Abigail Dougherty/Stuff National Party leader Judith Collins, Paul Goldsmith and Parmjeet Parmar talk to media at the bottom of Mt Roskill about the fail of light rail. The Government’s multi-billion dollar plan to build Auckland light rail – likely the most expensive infrastructure project in New Zealand’s history – didn’t analyse value for money when its final stage Cabinet paper was drawn up early last year. This was despite the Government spending more than two years investigating light rail proposals and $5 million on a process to work out who should even build it. It was only in February of 2020, when a draft Cabinet paper was being drawn up to finally select who would build and run the light rail line that Treasury, the Government’s economic policy shop, warned that any final decision should be delayed for another month because a standard cost-benefit analysis hadn’t been completed to find out whether the project was actually worthwhile.
