Executive Summary

New Zealand’s digital infrastructure is currently experiencing a significant acceleration in capital inflow. The market is rapidly evolving from a geographically isolated digital terminus into a strategic transit hub, supported by a mix of global hyperscalers, local telecommunications incumbents, and specialist operators.

Top-Level Growth Forecasts

The market forecast reveals massive, sustained expansion driven heavily by hyperscale demand:

• Capacity Growth: Total deployable capacity in New Zealand is forecast to grow from 128MW in FY25 to 343MW in FY30, representing a powerful Compound Annual Growth Rate (CAGR) of 21.8%.
• Hyperscale Dominance: Hyperscale volume (both external and internal) already constitutes more than half of deployable capacity as of FY25, a trend that will continue to accelerate as public cloud and AI workloads expand.
• Revenue & Pricing: Data centre lease revenue is projected to rise at a 22.2% CAGR across the forecast period. Due to supply constraints and high current occupancy rates, segment prices are expected to grow by approximately 6% out to FY30, but the growing share of lower-priced hyperscale capacity means that blended price growth is around 2%.
• Geographic Shift: While Auckland currently dominates with an 85% share of national capacity, upcoming mega-projects (particularly Datagrid’s massive planned facilities in Invercargill) are set to significantly expand the South Island’s market share in the coming years.

Our definition of “capacity” is deployable capacity that is already in the market, i.e. capacity that is either in use or ready to deploy on a timescale of weeks. Other capacity forecasts in the market may use more expansive definitions, the most common being “critical load” (or “IT load”), the power available for IT equipment (whether actually used or not). However, our definition allows us to calculate forecast revenues based on unit prices. 

Key market drivers

The surge in investment is underpinned by several primary catalysts:

• The Artificial Intelligence (AI) Boom: A global requirement for AI model training and inference is fundamentally altering technical requirements. Rack densities are being pushed from a standard 5-10 kW to beyond 20 kW, and up to 200 kW for specialized GPU clusters.
• Renewable Energy & Sustainability: New Zealand generates approximately 85% of its electricity from renewable sources, which appeals strongly to the ESG mandates of global hyperscalers..
• Data Sovereignty & IT region establishment: Underpinned by the Privacy Act 2020 and a government “Cloud First” mandate, New Zealand provides a stable jurisdiction for onshore hosting. The establishment of New Zealand IT regions by hyperscale operators in response is drawing in digital infrastructure investment.
• Subsea Connectivity: Investments in the Tasman Ring Network and the “Great Southern Route” are mitigating historic connectivity gaps, providing resilient, high-capacity links that bypass geopolitically contested areas like the South China Sea.

Despite robust drivers, the expansion of the data centre market faces several structural bottlenecks:

• Electricity Grid & Transmission Lag: The existing transmission infrastructure is under significant pressure, particularly in Auckland. With Transpower upgrade cycles extending 24 to 36 months, the “time to power” has become a primary bottleneck for project viability.
• Consenting Complexity & Land Scarcity: Finding appropriately zoned land that is close to fibre landing stations and high-capacity power nodes is a major challenge. Additionally, the Resource Management Act (RMA) and Overseas Investment Act introduce substantial administrative burdens and project delay.
• Construction Costs & Talent Shortages: New Zealand faces an acute shortage of specialized technical labor, compounded by elevated construction costs estimated at USD 12.3 per watt – significantly higher than neighbouring APAC markets.
• Resource Scrutiny: There is growing public and regulatory concern over the water consumption of traditional cooling systems, making water-efficient technologies essential for long-term operational licensing.
