Amped-up commercial assets

New Zealand’s commercial property sector is entering a new phase of operational scrutiny as tightening electricity supply, rising outgoings, and accelerating sustainability expectations converge to reshape how buildings are valued, leased, and future proofed.

Discussing the issue in its Total Property portfolio, Bayleys says the shift marks one of the most significant structural changes to asset performance with energy strategy now sitting firmly alongside location, amenity, and lease profile as a core determinant of competitiveness.

Across global markets, operating costs are rising and becoming more volatile, with energy taking a growing share of the pressure. Ageing infrastructure, lagging generation investment, and surging electrification demand are converging to tighten energy supply.

Knight Frank’s Data Centres Global Forecast Report 2026 highlights the rapid expansion of hyperscale and AI driven computing facilities as a major force reshaping power economics. These assets require large, continuous supply and are increasingly competing with cities and commercial buildings for long term availability.

New Zealand is not insulated from these forces, with multiple data centre proposals and Transpower’s signalling of future grid constraints pointing to a more contested energy environment. For commercial and industrial property owners, the question is no longer whether energy will influence asset performance, but how quickly they can adapt.

Bayleys’ Auckland Office Outgoings Benchmarking Report reinforces the point, concluding that without transparency, owners risk managing symptoms rather than causes. Procurement discipline around contract structure, renewal timing, fixed versus spot exposure, and alignment between load profile and contract design now directly influences long term cost stability. In a tightening market, procurement is becoming a competitive advantage.

Energy behaviour has become a landlord–tenant engagement issue, with transparency and governance increasingly influencing market perception, according to Bayleys national director of professional services, Stuart Bent.

“Tenants are now looking beyond just the rent line. Assets that show strong procurement discipline, efficient infrastructure, and tight operational control stand out on both cost and market appeal.

“Regardless of scale, we work closely with owners to manage operating expenses and identify efficiency gains that support stronger income growth over time.”

Bent notes that offshore mandates increasingly require minimum sustainability benchmarks, including Green Star ratings and robust reporting frameworks such as NABERSNZ and GRESB.

“Listed corporates must prove their sustainability credentials to keep stakeholders onside,” he says.

“That pressure is reshaping leases with more clauses on green procurement, shared data, and joint responsibility for sustainable operations.”

A clear divide is emerging in occupier behaviour, with smaller tenants under 500sqm typically not prioritising sustainability or energy credentials. But once space requirements exceed 1,000sqm, particularly for corporate head offices, sustainability becomes a core filter.

“OPEX pressure is growing with escalating rates, and insurance still biting hard despite some easing. Cost escalation is reshaping how value is assessed and even big occupiers with long wish lists expect sharp OPEX, so buildings that manage energy well rise to the top.”

A Bayleys -managed office portfolio recently rolled out solar across three buildings, improving sustainability ratings by reducing grid reliance and boosting competitiveness with newer stock. Senior facilities manager Mark Fogarin notes that solar unlocks value from an otherwise idle asset, the roof, but says the foundation of any strategy is understanding how the building actually works.

“Accurate metering and monitoring reveal where energy is used and why, enabling informed decisions about replacement systems and investment timing.”

Fogarin says landlords must increasingly decide whether to invest ahead of the market. Tenants with offshore sustainability mandates are already signalling they will not remain in buildings that have not electrified or moved off fossil fuels. For older buildings with vacancy, the motivation to upgrade is strongest.

For suitable multi-tenant assets, embedded networks can create a structure for owners to earn recurring infrastructure revenue from on-site electricity distribution arrangements, while preserving retailer choice for tenants.

“Many landlords don’t realise their building can support an embedded network, leaving money on the table which is where a switched on property manager matters. Valuers now recognise this as recurring annuity and today it’s proven and priced into income whereas years ago, it wasn’t,” says Fogarin.

Michael Peters, general manager of client success at energy and infrastructure advisory firm Tenco, says the strategic question for owners is shifting from price to capability.

“The practical question is no longer only ‘what will electricity cost?’ It is whether the property has the electrical capacity and flexibility to support how tenants will use energy over time.”

Regulatory change is reinforcing this shift. The Electricity Authority’s distribution connection pricing reforms, effective 1 April 2026, signal that network access is becoming a development and investment consideration, not a back office technicality.

Peters says electrical capacity should increasingly sit within purchaser due diligence.

“A property may have adequate supply for today’s use, but not for the next lease strategy or major plant replacement. Poor capacity planning can create avoidable upgrade costs, delay tenant works, constrain leasing options, or increase operating cost exposure.”
