Home-grown data centre operators Datavault and T4 New Zealand Data Centres are both expanding their infrastructure to meet growing national demand for secure, locally managed digital capacity. The two companies, which emphasise New Zealand ownership and data sovereignty, have announced new developments in Auckland and Wellington aimed at strengthening the country’s data-centre network and supporting enterprise and government workloads.
Datavault New Zealand, one of the country’s longest-established locally owned data-centre operators, has expanded its national footprint with an operations and management agreement of service provider Vital’s Wellington data centre located at Lambton Quay that includes full rebranding and integration into the DataVault operation – a full buyout is an option further down the track. The move comes after Tait Communications’ acquisition of Vital which had its origins in the 1990s as a fibre loop connecting Wellington City Council buildings and growing from that. Datavault will assume the operation and management of the facility from November.
“A modernisation program is planned to bring the site up to Tier 3 standards, aligning with the high expectations our clients have of our existing facilities,” said the company. The facility will be integrated into the Datavault brand and operation over several months.
The expansion adds to Datavault’s existing facilities in Auckland and Hamilton, extending its reach into the lower North Island and strengthening its position as a sustainable, carrier-neutral provider of colocation and connectivity services. By acquiring the Wellington facility, Datavault now covers all three of New Zealand’s major data-centre regions. The expansion bolsters its role as a sustainable and resilient alternative to larger international operators, catering to organisations seeking secure, locally managed colocation infrastructure.
The data centre operator has also expanded its Auckland data centre, unveiling its fourth data hall. Founded in 2004, Datavault operates purpose-built, Tier III-standard facilities designed for high availability, offering customers near-continuous uptime and redundant A and B power feeds. Its Auckland and Hamilton data centres feature seismic resilience, elevated and flood-safe locations, and energy-efficient infrastructure with a Power Usage Effectiveness (PUE) as low as 1.14.
Datavault’s sites are fully carrier-neutral, allowing customers to connect directly with their preferred network or cloud providers. It offers flexible colocation options ranging from half racks to private cages and supports high-density workloads up to around 15–20 kW per rack. The company also provides 24/7 access, remote-hands support, and custom infrastructure solutions tailored to enterprise and government workloads requiring local data sovereignty and low-latency performance.
The company promotes itself as New Zealand’s first sustainable colocation provider, incorporating solar generation and efficient cooling systems to minimise environmental impact.
T4 unveils Tihi Auckland
T4 New Zealand Data Centres has unveiled its new Auckland facility, known as Tihi which means summit or best, a Tier 3+ data centre designed by IBM and certified for use by New Zealand government agencies under the All-of-Government (AOG) and Department of Internal Affairs (DIA) frameworks. Located 30 metres above sea level, Tihi sits outside Auckland’s volcanic field and flood plains, and away from flight paths, offering a high level of physical resilience.
The site features dual power feeds, diverse fibre connectivity, and three separate transport routes, ensuring continuous operation and redundancy. T4 guarantees 100 per cent availability and holds ISO 9001, 14001 and 27001 certifications, covering quality management, environmental management, and information security standards. The facility’s location provides direct line of sight to Auckland’s Sky Tower, enabling strong connectivity and potential for low-latency communications. T4 describes Tihi as one of the few “non-compromised” data centre sites in the Auckland region, offering both physical and network diversity.
At the T4 launch, wholesale operator Chorus launched its new Express Connect service bringing high-speed, low-latency links that can be provisioned within four business hours in data centres where Express Connect is available – like Tihi. “Express Connect availability for our clients is further evidence of our commitment to a client-centric approach,” said T4’s Dean Addie.
“It has circa 500 rack spaces available and is the largest pillarless DC in NZ,” he added. “It has 250kW of chilled water available per rack for direct water cooling so ready for AI.”
T4 is 100 per cent New Zealand owned, with partial Māori ownership, positioning the company as a provider of sovereign digital infrastructure for government and enterprise customers seeking to retain data within Aotearoa. The expansion of Tihi underscores T4’s focus on delivering secure, sustainable, and sovereign data services to support New Zealand’s digital future.
