The Treasury believes the $5 -$7 billion expected from the partial sale of state assets should fund the Government's capital projects for the next six or seven Budgets.
Allocations of $557 million of the money were made in this year's Budget and are projected to rise to $1.2 billion in the 2013 Budget.
However documents provided to Minister of Finance Bill English in the leadup to this year's Budget showed 16 government agencies expected to submit plans for capital spending of $1.9 billion in the 2013 Budget round.
The Treasury says that, based on 10-year plans from the 16 agencies, money from the partial asset sales should account for capital spending for the next six or seven Budgets.
Allocations in this year's Budget showed the money, which is currently in the Government's Future Investment Fund, will go towards new schools, health, science and innovation projects, and the turnaround of KiwiRail.
