Whether you supply materials yourself or leave it to your handyman depends on the job, your budget, and how much time you want to invest. Both approaches are perfectly valid — the key is agreeing upfront so there are no surprises on the day.
The Case for Letting Your Handyman Source Materials
Most experienced handymen prefer to source materials themselves, and there are good reasons for this:
- They know what works. A good handyman has tried and tested products and knows which brands hold up in NZ conditions — whether that's coastal humidity, UV exposure, or the freeze-thaw cycles of the South Island.
- They get trade accounts. Many handymen have trade accounts at suppliers like Mitre 10, Bunnings, or PlaceMakers, which can mean better pricing or faster access to stock.
- They're responsible for the result. If they choose the materials, they own the outcome. If you supply the wrong product, the liability shifts to you.
- Less running around for you. Sourcing materials takes time — measuring, researching, driving to the store, and returning leftovers. Letting your handyman handle it saves you that hassle.
- Correct quantities. Tradespeople are experienced at calculating how much material a job needs, reducing waste and avoiding costly mid-job trips back to the store.
Typically, a handyman will charge a materials markup — often somewhere in the range of 10–20% above cost — to cover their time sourcing, transporting, and managing materials. This is standard practice and worth asking about upfront.
The Case for Supplying Materials Yourself
There are situations where supplying your own materials makes sense:
- You've already bought something. Maybe you picked up tiles, paint, or timber in a sale and want them used.
- You have a specific product in mind. If you've chosen a particular Resene colour or a specific James Hardie cladding product, buying it yourself ensures you get exactly what you want.
- You want full cost transparency. Buying materials yourself means you know exactly what you paid, with no markup.
- Smaller or simpler jobs. For a basic job like patching a wall with GIB board or touching up paint, picking up a few items yourself is straightforward.
If you do supply materials, make sure you discuss this with your handyman before the job starts. They may decline to use certain products they're unfamiliar with, or they may flag that what you've bought isn't suitable for the application.
Key Things to Discuss Before the Job
Whichever approach you choose, have a clear conversation covering:
| Topic | Why It Matters |
|---|---|
| Who buys what | Avoids duplication or gaps |
| Markup on materials | So you understand the full cost |
| Product specifications | Ensures the right product for the job |
| Receipts and invoicing | Useful for warranty claims or insurance |
| Leftover materials | Who keeps or disposes of them |
| Returns policy | Some stores require the original buyer to return goods |
Quality and Compliance Matter
In New Zealand, some work must meet the NZ Building Code, and the materials used play a big part in that. For example, exterior work involving weatherproofing must comply with Clause E2 (External Moisture), and using the wrong product — even if it looks similar — can cause compliance issues down the track.
For adhesives, waterproofing membranes, and structural fixings, always use products that are specified for the application. Brands like Sika, Ardex, and Mapei publish technical data sheets that specify where and how their products should be used. A knowledgeable handyman will be across this.
If you're unsure whether a project needs a building consent, check with your local council or visit MBIE Building Performance. Some work is exempt under Schedule 1 of the Building Act, but it's always worth confirming — don't rely on assumptions.
When to Call a Professional
Handymen are great for a wide range of general maintenance and repair tasks, but some work in NZ is legally restricted to licensed tradespeople:
- Electrical work — any work on fixed wiring must be done by a registered electrician. Check the Electrical Workers Registration Board (EWRB).
- Plumbing and gasfitting — restricted work must be carried out by a licensed plumber, gasfitter, or drainlayer. See the Plumbers, Gasfitters and Drainlayers Board (PGDB).
- Structural or complex building work — may require a Licensed Building Practitioner (LBP).
For these trades, the question of who supplies materials is secondary — make sure you're using the right person for the job first.
