GDP forecast to increase by $billions

New NZIER modelling from 2026 forecasts that the TWSP project will provide a significant increase to regional GDP by an additional net present value of $1 billion to $5 billion and 235-1,820 jobs (depending on land use change), which includes an increase in annual regional GDP of up to $700M and tax contribution of $200M per annum.

The construction phase alone is expected to generate 220-330 jobs and substantial economic activity across the region. During construction, GDP is expected to increase by between $166M to $346M and household spending is expected to increase by $177M.
