Ventia secures NZ$160 million Transpower contract extension

Ventia Services Group Limited (ASX: VNT) has secured a NZ$160 million contract extension with Transpower New Zealand Limited to operate, maintain, and provide specialist electrical services across New Zealand’s national electricity grid. The two-year extension, commencing in August 2027, continues a relationship spanning more than 30 years and covers services across both the North and South Islands.

The Ventia Transpower New Zealand Extension was built into the original Transmission Grid Services contract and Contestable Work Panels that commenced in 2022. Ventia currently services approximately one-third of Transpower’s network across two separate regions.

Key contract details:

  • Contract value: NZ$160 million
  • Duration: Two years
  • Commencement: August 2027
  • Geographic coverage: North and South Islands across two regions
  • Relationship length: 30+ years

Deepening a three-decade partnership

The contract extension reflects Ventia’s consistent operational performance and client retention strength in essential infrastructure services. Transpower operates New Zealand’s national electricity transmission network, making service continuity and safety-critical reliability fundamental requirements for contractors.

Dean Banks, Managing Director and Group CEO

“Our long-standing relationship with Transpower has been underpinned by consistent performance, collaboration and a shared focus on delivering safe and reliable energy infrastructure. We are pleased to be extending our partnership and look forward to continuing to grow our relationship and delivering the critical services that support New Zealand’s energy future.”

Long-tenure contracts in transmission grid services reduce re-tendering risk and provide revenue visibility through multi-year periods. The extension through 2029 demonstrates competitive positioning in a sector where operational track record and safety performance determine contract renewals.

Understanding transmission grid services contracts

Transmission grid services involve the operation, maintenance, and specialist electrical work required to keep high-voltage infrastructure functional. Transpower operates New Zealand’s national electricity grid, which connects power generation sources to regional distribution networks that supply homes and businesses.

These contracts typically span multiple years due to the specialised technical skills required, safety-critical nature of the work, and continuity requirements. Service providers must maintain certified electrical workers, comply with strict safety protocols, and demonstrate proven capability in live high-voltage environments.

Essential infrastructure services in transmission and distribution provide defensive revenue characteristics with low cyclical exposure compared to project-based construction work.

What the extension means for Ventia’s outlook

The Ventia Transpower New Zealand Extension contributes to contracted revenue visibility through to August 2029, supporting earnings predictability in the company’s essential infrastructure portfolio. Ventia operates across multiple infrastructure sectors with a combined workforce exceeding 35,000 people across more than 400 sites in Australia and New Zealand.

Contract Detail Specification
Contract Value NZ$160 million
Duration Two years
Commencement August 2027
Coverage North and South Islands
Relationship Length 30+ years

The company’s strategy centres on customer retention and service excellence across defence, social infrastructure, water, electricity and gas, resources, telecommunications, and transport sectors. Multi-year contract extensions in essential infrastructure align with this positioning by reducing revenue volatility and supporting margin stability.

Next steps and timeline

The extension commences in August 2027, with current contract arrangements and contestable work panels continuing until that date. No further action is required, as the extension was built into the original 2022 contract structure.

Key timeline:

  1. Original contract commenced: 2022
  2. Extension commencement: August 2027
  3. Extended contract conclusion: August 2029

The extension provides Ventia with contracted revenue through to mid-2029 and continues service delivery across approximately one-third of Transpower’s transmission network in New Zealand.
