New Zealand Data Center Market Size, Share and Outlook - Growth Analysis Report and Forecast Trends (2026-2035)

Market Overview

The New Zealand data center market is moving from a small enterprise hosting sector to a capacity-led infrastructure class. Local cloud regions, sovereign data rules and artificial intelligence workloads are pulling investors towards Auckland and, increasingly, regions with spare renewable power.

Three forces shape the market: public cloud regions that keep data onshore, government and enterprise preference for locally controlled facilities, and electricity access, because several proposed campuses are sized against national power demand and must show new generation to proceed.

In September 2025 Amazon Web Services opened its Auckland region, and in January 2026 Spark completed the sale of 75% of its data center business to Pacific Equity Partners. In July 2026 the Prime Minister said hyperscale operators must add new generation.

Key Market Trends and Insights

• Hyperscale regions arrive: Amazon Web Services committed NZ$7.5 billion to its Auckland region, which reached general availability in September 2025 with three availability zones.
• Carve-out creates a new operator: TenPeaks Data Centres began with 23 MW of operating capacity across 11 facilities and a development pipeline above 130 MW after the January 2026 Spark carve-out.
• Regional power-led campuses: Datagrid secured full resource consent in March 2026 for a campus of up to 280 MW at Makarewa near Invercargill, backed by a 140 MW power option.
• Sovereign capacity consolidates: Datacom bought T4's Tihi data center in Auckland in April 2026, adding roughly 500 rack spaces and bringing its New Zealand network to five data centers.

New Zealand Data Center Market Size and Forecast

The market is shifting from small enterprise server rooms towards purpose-built colocation and hyperscale campuses designed for dense artificial intelligence loads. Retail colocation still serves most local enterprises, while wholesale capacity advances fastest as cloud providers and large tenants contract in bulk. Cloud and hyperscale providers become the most dynamic customer group, and facilities above 100 MW emerge from a small base as proposals move through consenting. Auckland remains the dominant region because of cable landings and customer density, while regions with generation capacity grow quickest. Government compacts on additional electricity supply, sovereign hosting requirements and liquid cooling retrofits point to a durable structural build-out rather than a short cycle.

Key Takeaways: New Zealand Data Center Market

Cloud Regions and Sovereign Demand Lift Revenue

Revenue is on course to more than triple, from USD 430.00 million in 2025 to USD 1,594.11 million in 2035 at a 14.0% CAGR. The Auckland regions of Amazon Web Services and Microsoft keep data onshore and pull enterprise, public sector and tenant demand into local facilities.

Wholesale Capacity and Large Campuses Lead Growth

Retail colocation holds the largest share, but Wholesale Colocation grows at an estimated 17.0% CAGR and facilities above 100 MW at an estimated 19.5% CAGR through 2035. TenPeaks, Datagrid and Contact Energy with CDC Data Centres each reported multi-site pipelines in 2026.

Power Access Becomes the Gating Factor

Government policy in 2026 ties large data centers to new electricity supply, so developers with generation partners hold the strongest position. Regions with spare renewable output grow fastest, while Auckland stays the largest base.

• Mercury signed a 15-year option for 140 MW with Datagrid in March 2026
• Contact Energy and CDC are studying 250 MW at Stratford, Taranaki
• The Prime Minister backed an additionality test in July 2026
