Internal Mall Hoardings in New Zealand – Questions & Answers

Are internal hoardings in malls exempt from structural, wind, or impact requirements?

No.
Internal hoardings in malls are not exempt from structural, wind, or impact requirements. In many cases, they are subject to higher engineering and safety standards due to crowd loading, pressure differentials, and asset owner requirements.

Being installed indoors or described as “temporary” does not remove the obligation to comply with New Zealand building and safety standards.

Are internal hoardings regulated under New Zealand law?

Yes.
Under the Building Act 2004 and the New Zealand Building Code, internal hoardings are considered building structures, even when installed temporarily.

There is no legal exemption simply because a hoarding is:

Inside a shopping centre

Temporary in nature

Installed for fit-out or demolition works

All hoardings must comply with relevant Building Code clauses, particularly those relating to structural stability and public safety.

Why are internal mall hoardings often considered higher risk than external hoardings?

Internal mall hoardings are typically installed in high-occupancy, fully operational public environments.

They are commonly located:

Along active pedestrian malls

Near major retailers and food courts

Adjacent to kiosks and common areas

At mall entrances and through-connections

These conditions significantly increase:

Pedestrian and trolley impact risk

Crowd loading during peak trading

Consequences of structural failure

As a result, internal hoardings are often treated as high-risk temporary structures, sometimes requiring more stringent controls than external site hoardings.

Do internal hoardings need to be designed for wind loading?

Yes — in many cases they do.

A common misconception is that wind loading only applies to outdoor structures. In reality, internal hoardings can be affected by wind and pressure effects, including:

Direct exposure at mall entrances

Through-connections to carparks or loading docks

Demolition works that open the building envelope

Smoke exhaust plenums

HVAC and pressure-controlled environments

Because of this, AS/NZS 1170.2 (Structural Design Actions – Wind) is frequently applied to internal mall hoardings, with wind pressures determined by a structural engineer or a wind study.

What impact and crowd loading requirements apply to internal hoardings?

Internal hoardings are continuously exposed to:

Pedestrian contact

Shopping trolley impact

Accidental collisions

Crowd pressures during peak trading

Emergency evacuation loads

To manage these risks, internal hoardings are commonly required to comply with:

AS 4687 / AS 4687.3 – impact resistance, overturning, and anti-climb performance

AS/NZS 1170.1 – imposed and crowd loading

NZ Building Code Clause F4 – safety from falling and impact

In many mall environments, these requirements exceed those applied to standard external hoardings.

Is building consent always required for internal hoardings?

Not always — but lack of building consent does not mean lack of compliance.

Even where a building consent is not required, internal hoardings must still:

Comply with the Building Code

Meet Health & Safety obligations

Satisfy asset owner requirements

Shopping centre owners often impose mandatory standards that go beyond council requirements.

What additional requirements should shopping centre owners impose?

Mall owners and operators need to ask for:

Engineer-certified hoarding systems

Defined wind and impact load ratings

Compliance with centre-specific fire and egress plans

Formal approval of documentation before installation

Ongoing inspection and maintenance regimes

Failure to meet these requirements can result in:

Installation delays

Forced removal of hoardings

Programme overruns

Increased liability exposure

These requirements are contractual and enforceable, regardless of council consent status.

Why is engineer certification critical for internal hoardings?

Internal mall hoardings are often:

Custom in height and width

Installed on uneven slabs or ramps

Exposed to wind, pressure, and crowd loads

Located in high-consequence public areas

Generic or non-engineered hoarding systems are not suitable for these conditions.

An engineer-certified hoarding system provides:

Verified structural capacity

Defined installation limits

Compliance with NZ Building Code requirements

Confidence for asset owners, councils, and insurers

Reduced approval and compliance risk

What standards are typically used to engineer internal hoardings?

Internal hoardings are commonly engineered to:

AS/NZS 1170.2 – wind actions

AS/NZS 1170.1 – imposed and crowd loads

AS 4687 / AS 4687.3 – impact, overturning, and anti-climb performance

NZ Building Code B1 – structure

NZ Building Code F4 – safety from impact and falling

These standards are widely accepted by councils, engineers, and major retail asset owners in New Zealand.

How does FTH Group approach internal mall hoardings?

FTH Group designs and supplies engineered hoarding systems specifically for internal mall environments in New Zealand.

Our hoardings are:

Engineered for wind, impact, and crowd loading

Certified by structural engineers

Compliant with NZ Building Code clauses B1 and F4

Aligned with AS/NZS 1170 and AS 4687 standards

Accepted by major retail asset owners

Suitable for custom heights, widths, and layouts

This ensures internal hoardings are not only visually compliant, but structurally safe and fit for purpose.

What is the key takeaway for tenants and property owners?

Internal mall hoardings are not a simplified compliance scenario.

In many cases, they are subject to higher engineering and safety requirements than external hoardings. Treating them as low-risk temporary barriers exposes tenants and property owners to unnecessary safety, compliance, and programme risk.

Proper engineering, certification, and design are essential to protecting the public and delivering compliant outcomes.
