To bridge the gap between tax revenue and government expenditure by promoting quantitative easing (QE) through strategic investments in infrastructure, thereby stimulating economic activity, employment, and tax base expansion.

Overview:

Simplified Tax System:
Flat Tax Rate: Implement a flat tax rate for all income levels to simplify the tax system, reduce compliance costs, and increase transparency. This rate would be set to ensure broad participation in the tax system while still providing enough revenue.
Broad Tax Base: Eliminate numerous tax exemptions and deductions to widen the tax base, ensuring more individuals and businesses contribute at a lower, consistent rate.
Incentivized Workforce:
Tax Incentives for Employment: Offer tax credits or reductions for businesses that increase their workforce, particularly in sectors like construction, technology, and renewable energy, which are critical for infrastructure development.
Education and Training Grants: Provide grants or tax benefits for individuals pursuing education or training in fields relevant to infrastructure projects, increasing employability and economic productivity.
Infrastructure Investment via QE:
Quantitative Easing for Infrastructure:
Bond Purchases: The Reserve Bank of New Zealand (RBNZ) would engage in QE by purchasing government bonds specifically aimed at funding large-scale infrastructure projects. These bonds would be issued for projects with high economic multipliers, focusing on areas like:
Transport Networks: Including roads, public transit systems, and airports.
Green Energy: Investments in renewable energy sources to reduce long-term energy costs and environmental impact.
Digital Infrastructure: Enhancing broadband and connectivity nationwide to support  digital services.
Housing and Urban Development: Projects that promote affordable housing and sustainable urban development.
Long-term Economic Benefits:
Job Creation: Immediate boost in employment in construction and related sectors, which in turn increases tax revenue due to higher employment rates and consumer spending.
Economic Stimulus: Infrastructure projects directly contribute to GDP growth, providing a long-term increase in the tax base through improved economic conditions.
Inflation Management: Carefully manage the injection of money to ensure it does not lead to runaway inflation, balancing QE with productivity gains from infrastructure.
Funding and Financial Strategy:
Debt Management: Instead of viewing public debt as a burden, view it as an investment in future economic stability. The debt incurred through bond issuance would be offset by:
Revenue from Increased Economic Activity: As infrastructure improves, so does the economic output, leading to higher tax revenues over time.
Asset Creation: Infrastructure itself becomes a national asset, potentially generating revenue or reducing costs in other areas (e.g., lower maintenance costs due to new constructions).
Public-Private Partnerships (PPPs): Encourage partnerships for project financing where possible, reducing the direct financial burden on the government while still achieving public benefits.
Policy Transparency and Accountability:
Performance Indicators: Establish clear metrics for each infrastructure project concerning economic return, job creation, and environmental impact to ensure accountability.
Public Reporting: Regularly report on the progress, economic impact, and fiscal implications of these investments to maintain public trust and support.
Legal and Regulatory Adjustments:
Fast-Track Consenting: Implement or enhance mechanisms for faster project approvals without compromising environmental or safety standards.
Legislation for QE: Ensure there's a legal framework allowing the RBNZ to engage in QE specifically for infrastructure, with defined parameters to control economic impacts.

Conclusion:
These values leverage the dual benefits of a simplified tax system and strategic quantitative easing to fund infrastructure, aiming to create a virtuous cycle of economic growth, employment, and increased tax revenues. By focusing on projects with high multiplier effects, the government can address fiscal shortfalls while improving the quality of life and economic competitiveness of New Zealand.
