The agency would be tasked with exploring public-private partnerships - agreements between the Government and the private sector - as a way to deliver new infrastructure projects.
Bishop said a new consenting framework for infrastructure investment would be developed to fix extensive delays and cost pressures within the consenting process.
According to the Infrastructure Commission, there had been a 150 per cent increase in the time it took to get a consent over a five-year period. The cost of consenting as a proportion of a project’s overall budget had also increased by 70 per cent over the last seven years.
The party’s two key changes to consenting would be to introduce a “fast-track process modelled on the Covid fast-track process for quick processing of resource consents”, the document said.
It would also establish a class of projects known as Major Infrastructure Priorities which would require decisions within a year.
An infrastructure plan for the next 30 years would also be developed for all sectors and broken down by city and region.
“We will establish national, city and regional ‘Deals’. These agreements will be long-term programmes of investment between regions and central government, spanning transport, rail, housing and other investments,” Bishop said.
