- New Zealand companies continued to invest in electrification, renewable generation, network resilience and greener buildings, although decarbonisation pathways remain uneven across sectors.
- Prominent social themes included customer affordability, workforce engagement, safety culture and deeper relationships with iwi, communities and suppliers.
- Governance disclosures placed clear emphasis on climate execution, cyber resilience, AI oversight, regulatory risk and board renewal, but some companies continued to face material governance or legal issues.
New Zealand’s 2026 reporting season showed many companies moving from broad sustainability commitments toward practical execution. Across the companies reviewed, ESG disclosures were increasingly linked to capital allocation, operational resilience and risk management. These disclosure trends are occurring against a backdrop of regulatory reform and challenging operating conditions in some sectors.
The season also highlighted a widening maturity gap. Some issuers are accelerating transition-related investment, while others remain constrained by technology, economics or policy settings. As a result, the quality of disclosure and credibility of execution are becoming increasingly important when assessing companies’ headline commitments.
Climate transition, resilience and disclosure
The energy transition remained the clearest area of momentum. Renewable generators continued to deploy capital at scale. Mercury, Meridian, Contact and Genesis are all progressing material generation, storage and flexibility projects. Contact’s retirement of the Taranaki Combined Cycle plant and 98% renewable generation mix marked a significant step down in its operational emissions profile, while Mercury and Meridian continued to broaden their renewable development pipelines. Genesis also progressed solar, battery and customer flexibility initiatives, even as it acknowledged the difficulty of meeting its FY30 interim science-based generation intensity target under expected market conditions.
Infrastructure resilience was also prominent. Vector’s record electricity network investment and decade-long capital programme reflect the need to support Auckland’s electrification while maintaining affordability and reliability. Chorus is accelerating copper retirement and positioning fibre as a more energy-efficient and weather-resilient technology. Port of Tauranga’s Stella Passage development could support capacity, automation, safety and emissions efficiency if progressed successfully. In property, Precinct and Property for Industry continued to increase the share of Green Star-rated assets, linking sustainability features to tenant demand, building performance and green finance flexibility.
Changes to New Zealand’s climate-related disclosure settings were a notable feature of the season. Several companies that are no longer expected to fall within the mandatory climate-reporting regime signalled that they would continue to disclose selected climate information voluntarily. SkyCity, Sky Network Television, Steel & Tube, Tourism Holdings and Winton all reflected this shift in different ways. The practical effect is that investors may receive less standardised disclosure from some issuers, particularly where full climate statements are no longer required, but a number of companies still appear to recognise the value of maintaining core emissions data, climate risk oversight and transition-related commentary.
People, customers and communities
Social performance was a strong feature across reporting, particularly where companies linked people and customer outcomes to business resilience. Energy retailers placed increased emphasis on hardship support, affordability and practical customer tools, including initiatives from Mercury, Meridian, Genesis and Contact. These programmes highlight the growing importance of customer trust as electrification increases electricity’s role in household and business budgets.
Workforce engagement and safety outcomes were generally constructive, although still varied by sector. Spark’s engagement score recovered from the prior year’s low point following significant organisational change, while Vector, Meridian, Genesis, Chorus, SkyCity, Precinct and Property for Industry all reported relatively strong engagement or customer satisfaction indicators. Safety performance improved meaningfully for several companies, including Mercury, Freightways, Tourism Holdings and Port of Tauranga on selected measures, but contractor safety, manufacturing risk and high-risk operational environments remain areas requiring ongoing attention. Several companies also invested in safety culture, critical risk frameworks or AI-enabled monitoring or leadership programmes, reflecting a more proactive approach to operational risk.
Relationships with mana whenua and local communities were another recurring theme. Renewable development, infrastructure investment, property development and port expansion all require strong social licence, particularly where projects interact with water, land, biodiversity, cultural values or local employment. Contact’s Hui Taumata, Meridian’s Waitaki rūnaka commitments, Mercury’s project partnerships and Port of Tauranga’s engagement on Stella Passage all demonstrate the growing importance of embedding these relationships into project planning and execution.
Governance, technology and execution risk
Governance disclosures continued to evolve beyond traditional board composition and remuneration topics. Cybersecurity, data privacy, and AI governance were increasingly visible across company reports. The strongest examples moved beyond generic references to innovation and disclosed how AI is being deployed, governed and integrated into workforce and operational strategy. Chorus stood out for the scale of adoption and its portfolio of use cases, Vector for applying AI to infrastructure resilience and asset management, and Spark for placing responsible AI within its formal ESG governance framework.
Board and leadership renewal was another common theme. Mercury, Spark, Freightways, Steel & Tube, Winton, Meridian, Contact, Tourism Holdings and Vector all disclosed notable changes. In many cases these changes appear orderly and aligned with succession planning, but some situations raise more material governance considerations. Winton remains the clearest example, with acknowledged non-compliance against several NZX Corporate Governance Code recommendations, significant leadership change after balance date and a board structure undergoing transition. SkyCity also remains governance-intensive given casino licensing, AML/CFT, host responsibility and Adelaide regulatory matters. Fletcher Building continues to face legal and regulatory issues related to Iplex Australia, Winstone Wallboards and historical Building + Interiors disclosures.
Executive remuneration disclosures show ESG and risk metrics being integrated into incentive structures, although the depth and weighting differ considerably. Climate, safety, customer, people and risk outcomes appeared in short-term incentive frameworks across a range of companies. Some companies also updated remuneration structures to include deferred equity, shareholding requirements or revised long-term incentive design. This is a positive direction where measures are material, clearly disclosed and aligned with long-term value creation. However, investors will still need to assess whether ESG metrics are sufficiently stretching and whether boards apply discretion appropriately when financial or risk outcomes warrant it.
Looking ahead
The 2026 reporting season suggests the approach of New Zealand companies is evolving in how they describe ESG risks and opportunities, while also revealing material differences in maturity and execution across companies. Investors should look beyond whether targets are in place and assess the credibility of execution: whether capital allocation supports the stated strategy, whether customer and community outcomes are managed alongside growth, whether boards have the capability to oversee emerging technology and regulatory risks, and whether disclosures remain useful as mandatory reporting requirements ease.
Key areas to watch over the coming year include delivery of major renewable and network investment programmes, the evolution of voluntary climate disclosure, social licence for infrastructure and development projects, cyber and AI governance, and affordability pressures across essential services. In Harbour’s view, disciplined execution and stakeholder trust may support long-term value creation, although outcomes will depend on company-specific governance, sector economics, regulation and delivery. The reporting season showed continued activity across these themes, but progress and disclosure quality remained uneven.
