Yes — installing a hasp and staple on a shed is one of the more approachable DIY security jobs around the home. It requires no licensed trade work, no building consent, and only basic tools. That said, doing it properly makes a real difference to how secure your shed actually is, so it's worth taking a few extra minutes to get it right.
What Is a Hasp and Staple?
A hasp and staple is a two-part locking mechanism. The hasp is a hinged metal strap that swings over a fixed loop called the staple (sometimes called the keeper). You then pass a padlock through the staple to hold everything shut. They're widely used on garden sheds, garages, gates, and storage boxes throughout New Zealand.
Tools and Materials You'll Need
Before you start, gather the following:
- Hasp and staple set (see hardware notes below)
- Padlock (sold separately)
- Power drill and drill bits
- Screwdriver or impact driver
- Tape measure and pencil
- Safety glasses
- Coach bolts or security bolts (strongly recommended — see below)
- Spanner or socket set if using bolts
- Wood chisel (optional, for recessing)
You'll find hasp and staple sets at Bunnings, Mitre 10, and PlaceMakers in a range of sizes and materials.
Choosing the Right Hardware
Not all hasps and staples are equal. Here's what to look for:
| Feature | Budget Option | Better Security Option |
|---|---|---|
| Material | Zinc-plated mild steel | Stainless steel or hardened steel |
| Fixings included | Short wood screws | Coach bolts or security screws |
| Hasp width | 50–75 mm | 100 mm+ |
| Padlock shackle clearance | Standard | Shrouded or close-shackle |
Stainless steel is worth the extra cost in coastal or high-humidity NZ environments — mild steel hasps can rust quickly in places like Auckland, Wellington, or anywhere near the sea.
For the padlock itself, look for a close-shackle or shrouded padlock with a hardened steel body. These are much harder to cut with bolt cutters than a standard open-shackle padlock.
Step-by-Step Installation
1. Mark Your Position
Close the shed door and mark where the hasp and staple will sit — typically at mid-height or in the upper third of the door. Make sure the hasp lines up squarely with the door frame or wall.
2. Pre-Drill Your Holes
Always pre-drill to avoid splitting the timber, especially on older sheds. Use a drill bit slightly smaller than your screw or bolt diameter.
3. Fix the Staple First
Attach the staple (the loop part) to the door frame or shed wall. This is the piece that takes the most force if someone tries to break in, so fix it solidly into a stud or solid timber — not just into cladding or thin ply.
4. Fix the Hasp to the Door
Swing the hasp into position over the staple and mark the fixing holes on the door. Drill and fix the hasp.
5. Use Coach Bolts, Not Just Screws
This is the most important security upgrade you can make. Standard wood screws can be ripped out with a crowbar in seconds. Coach bolts (also called carriage bolts) pass right through the door or frame and are secured with a washer and nut on the inside — making them extremely difficult to remove from outside. Use at least two bolts per plate where possible.
6. Test the Fit
Close the hasp over the staple and check it moves freely, sits flush, and the padlock fits through the staple loop without forcing.
Common Mistakes to Avoid
- Fixing into thin cladding only — always locate a stud or solid backing timber
- Using the screws that come in the pack — they're usually too short and too soft; upgrade to longer, hardened fixings or coach bolts
- Leaving bolt heads exposed on the outside — use coach bolts with a domed head that can't be gripped by a spanner
- Choosing an open-shackle padlock — these are easy targets for bolt cutters
Does This Need a Building Consent?
Fitting a hasp and staple to an existing shed is minor maintenance work and does not require a building consent. However, if you're building a new shed or making structural changes, different rules may apply. Always check with your local council if you're unsure — the MBIE Building Performance website has useful guidance on Schedule 1 exemptions.
When to Call a Professional
For a basic hasp and staple, most homeowners can manage the job themselves. However, consider calling a qualified locksmith if:
- You want a higher-security locking solution such as a deadbolt, mortice lock, or electronic lock fitted to your shed
- The shed door or frame is damaged, rotten, or misaligned and needs repair before a lock will work properly
- You're securing a shed that stores high-value tools, equipment, or hazardous materials and want professional advice on the best setup
A qualified locksmith can assess your shed and recommend the most effective solution for your situation. You can find licensed locksmiths near you on tradedirectory.co.nz.
Safety Note
Wear safety glasses when drilling, especially into older timber that may splinter. If your shed is older and you suspect the timber may contain lead paint, take care when drilling and sanding — check the WorkSafe NZ guidance on working safely with lead paint.
