Case Study: Earthquake Risk and Tenant Disruption in Wellington Offices

Introduction

In commercial property, risk is not always financial or market-driven. In some locations, physical factors play an equally important role.

In Wellington, earthquake risk is a key consideration for property owners, investors and tenants. The city’s location on active fault lines means that building strength and structural performance are critical to long-term asset success.

For commercial office properties, this creates a unique challenge. Buildings that do not meet modern earthquake standards can face tenant disruption, vacancy risk and significant capital costs.

The Context: Earthquake Standards and Building Performance

Commercial buildings in New Zealand are assessed based on their ability to withstand earthquakes, often measured as a percentage of the New Building Standard (NBS).

Older buildings, particularly those constructed before modern codes, may fall below acceptable thresholds. When this happens, property owners may be required to:

• Undertake structural upgrades

• Strengthen key building systems

• Or in some cases, vacate tenants until works are completed

These requirements are not always predictable in timing or cost, making them a major consideration in asset management.

The Impact on Tenants

For tenants, earthquake-related building issues can be highly disruptive.

Relocation may be required at short notice, leading to:

• Business interruption

• Fit-out costs that cannot be recovered

• Loss of operational continuity

Even where buildings remain occupied, perceived risk can influence tenant decisions. Businesses are increasingly prioritising safety, compliance and long-term stability when selecting office space.

This has contributed to shifting demand toward newer, higher-grade buildings.

The Impact on Property Owners

For landlords, earthquake risk introduces both operational and financial challenges.

1. Capital Expenditure

Seismic upgrades can be costly, often requiring significant investment to bring buildings up to standard. Without planning, these costs can place pressure on cash flow and returns.

2. Vacancy and Income Disruption

If tenants are required to vacate, rental income may be reduced or lost entirely during upgrade periods. Re-leasing can also take time, particularly if competing buildings offer higher perceived safety.

3. Asset Value and Market Positioning

Buildings with lower seismic ratings may become less competitive in the leasing market. Over time, this can impact both occupancy levels and asset value.

In contrast, well-upgraded or modern buildings often benefit from stronger tenant demand and more stable performance.

A Shift in Market Behaviour

Earthquake risk has contributed to a broader trend in Wellington’s office market.

Tenants are increasingly:

• Moving toward higher-quality, compliant buildings

• Prioritising long-term security and operational certainty

• Avoiding older buildings with potential upgrade risk

This aligns with the wider “flight to quality” trend seen across commercial property markets.

Key Takeaways for Property Owners

Earthquake risk highlights the importance of a proactive and structured approach to asset management.

Property owners should consider:

• Forward planning for capital expenditure related to building upgrades

• Regular assessment of building performance and compliance

• Clear communication with tenants regarding building status and future works

• Strategic positioning to remain competitive in a changing market

A reactive approach can lead to sudden disruption and higher long-term costs. In contrast, early planning and investment can protect both income and asset value.

The Bottom Line

In Wellington, earthquake risk is not a theoretical concern — it is a practical factor that directly influences commercial property performance.

Buildings that fail to meet modern standards can face tenant disruption, increased vacancy and significant capital requirements. Those that are proactively managed and upgraded are better positioned to retain tenants and maintain long-term value.

For property owners, understanding and planning for these risks is essential to building a resilient and high-performing portfolio.
