Yes, as a homeowner in New Zealand you can generally erect a basic two-bay mobile scaffold tower for gutter cleaning yourself — but only if you follow strict safety guidelines and stay within certain height limits. Getting it wrong can be fatal, so it pays to understand the rules before you start.
What the Law Says in New Zealand
Scaffolding work in NZ is governed by the Health and Safety at Work Act 2015 and associated regulations. Under WorkSafe NZ guidelines, scaffolding over 5 metres in height must be erected, altered, or dismantled by a competent person — and for anything over 5 m, that typically means a licensed scaffolder. For a domestic homeowner doing their own gutter cleaning on a single-storey or low two-storey home, a two-bay mobile tower that stays under 5 m working height is generally within reach of a careful DIYer, provided you follow the manufacturer's instructions to the letter.
If your gutters are higher than 5 m from the ground, stop here and hire a professional scaffolder — you can find qualified local scaffolders on tradedirectory.co.nz.
Understanding Tower Scaffold Components
A typical mobile aluminium scaffold tower consists of:
- End frames (the A-frame or ladder-frame uprights)
- Horizontal braces and diagonal braces (for rigidity)
- Decking boards or platform (the working surface)
- Guardrails and toe boards (fall prevention)
- Castors with locking brakes (for mobility)
Two-bay refers to a tower with two bays in length (the space between uprights), giving you a longer working platform and more room to move along the gutter line. Most hire companies supply towers in modular kits with assembly instructions — always use the instructions supplied with that specific system, as designs vary.
Key Safety Rules to Follow
Height-to-Base Ratio
This is the most critical rule. For outdoor use, the height of the platform should be no more than 3 times the shortest base dimension. For example, if your tower base is 1.2 m wide, the platform must not exceed 3.6 m high. Exceeding this ratio dramatically increases the risk of toppling.
Always Lock the Castors
Before stepping onto the platform, lock all four castor brakes. Never move the tower while anyone is on it.
Guardrails Are Not Optional
Fit guardrails on all open sides of the platform at approximately 900–1000 mm high, plus a mid-rail and toe board. This is a WorkSafe requirement, not a suggestion.
Ground Conditions
Ensure the ground is firm, level, and stable. Soft or sloped ground is dangerous — use base plates or adjustable screw legs to level the tower. Never erect a scaffold tower on a slope without proper levelling equipment.
Never Overload the Platform
Check the manufacturer's rated load capacity (typically 225–275 kg for a standard hire tower). That includes you, your tools, and any debris.
Weather
Do not use a scaffold tower in winds above 40 km/h or in wet, icy, or slippery conditions.
Hiring vs. Buying a Tower
For a one-off gutter clean, hiring a tower is almost always the better option. Hire costs vary by region and tower size — as a rough guide, expect to pay somewhere in the range of $80–$200 per day for a basic aluminium tower hire, though you should get quotes locally as prices differ. Bunnings and Mitre 10 also stock smaller platform ladders and work platforms that may suit single-storey jobs:
If you're buying, look for a tower that complies with AS/NZS 1576 (the scaffolding standard) — check Standards NZ for details.
Building Consent — Do You Need One?
For a temporary mobile scaffold tower used for maintenance (not construction), building consent is not required. Temporary access equipment for cleaning or maintenance falls outside the Building Act consent requirements. However, if you're unsure, always confirm with your local council.
Step-by-Step Assembly Overview
- Read the manufacturer's instructions fully before touching any components.
- Lay out all parts and check nothing is damaged or missing.
- Assemble the base frame on level ground with castors locked.
- Build up the frame sections one level at a time, fitting braces as you go.
- Fit the platform deck securely — it should not rock or slide.
- Install guardrails, mid-rails, and toe boards on all open sides.
- Double-check the height-to-base ratio before climbing.
- Have a second person present whenever possible — both for safety and to pass tools.
When to Call a Professional
Call a licensed scaffolder if:
- Your gutters are higher than 5 m from the ground
- The ground is sloped, soft, or uneven and cannot be properly levelled
- You need to work near power lines (contact your lines company first — this is a serious hazard)
- You feel unsure at any point about the assembly or stability
- The job requires the tower to be in place for more than a day or two
Working at height is one of the leading causes of serious injury and death in New Zealand. WorkSafe NZ has clear guidance on working at height safely. A qualified scaffolder will assess your site, erect a compliant structure, and take on the liability — that peace of mind is worth a lot. Find a local scaffolder on tradedirectory.co.nz.
