More than $70 billion dollars has been set aside by the government for new and existing infrastructure projects over five years following yesterday's budget.
Capital spending will average $18.5 billion per year for the next three years, up from $9.7 billion in the past three years.
A large part will be for flood and cyclone recovery.
Infrastructure New Zealand's chief executive, Nick Leggett, spoke with Ingrid Hipkiss.
