Choosing a paint colour is only half the battle — the finish (or sheen level) you pick can make or break the final result. Whether you're repainting a lounge, freshening up a bathroom, or tackling a full interior repaint, understanding the difference between matt, low-sheen, and semi-gloss will save you time, money, and frustration down the track.
What do sheen levels actually mean?
Paint sheen refers to how much light a dried paint film reflects. The more sheen, the more light bounces back at you — and generally, the harder and more washable the surface. Manufacturers measure sheen using a gloss meter, but in practical terms, the categories you'll encounter most in NZ homes are:
- Matt (flat) — little to no reflectivity; soft, chalky appearance
- Low-sheen (also called eggshell or satin) — a subtle, velvety glow
- Semi-gloss — noticeably shiny, easy to wipe clean
Brands like Resene and Dulux each have their own product lines across these categories, and the exact sheen level can vary slightly between brands, so it pays to check the technical data sheet before you buy.
Matt paint: the overview
Matt finishes absorb light rather than reflecting it, which gives walls a rich, deep colour and hides surface imperfections beautifully. This makes matt ideal for older homes with textured or slightly uneven walls — common in NZ villas and bungalows with lath-and-plaster construction.
The trade-off is durability. Traditional matt paints mark and scuff more easily, and scrubbing can leave shiny patches. Modern washable matt formulations (such as Resene SpaceCote Flat or Dulux Wash & Wear Matt) have improved significantly, but they still lag behind higher-sheen options in high-traffic areas.
Best for: Ceilings, formal living rooms, bedrooms, feature walls, and rooms where you want to minimise the appearance of wall imperfections.
Low-sheen paint: the overview
Low-sheen (sometimes labelled eggshell or satin) sits in the sweet spot between matt and semi-gloss. It offers a soft, warm glow that looks elegant without being obviously shiny. It's also meaningfully more durable and washable than matt, making it the go-to finish for most NZ interior walls.
BRANZ, New Zealand's building research authority, generally recommends low-sheen or semi-gloss for areas subject to moisture and condensation — an important consideration given NZ's variable climate and the requirements of the Healthy Homes Standards for adequate ventilation.
Best for: Living areas, hallways, bedrooms, children's rooms, and as a versatile all-rounder across most of the house.
Semi-gloss paint: the overview
Semi-gloss has a clearly reflective surface that's tough, moisture-resistant, and very easy to wipe down. It's the standard choice for trims, architraves, skirtings, and doors — and it's well-suited to kitchens and bathrooms where steam, grease, and splashes are part of daily life.
The downside: semi-gloss shows every bump, crack, and imperfection in your walls. Surface preparation becomes critical. It can also look clinical or harsh if used across large wall areas in living spaces.
Wattyl and other NZ paint brands offer semi-gloss in both water-based and oil-based formulations. Water-based semi-gloss has improved enormously and is now the preferred choice for most interior applications — easier to apply, lower VOCs, and faster drying.
Best for: Kitchens, bathrooms, laundries, trims, doors, skirtings, and any surface that needs regular cleaning.
Head-to-head comparison
| Criteria | Matt | Low-sheen | Semi-gloss |
|---|---|---|---|
| Reflectivity | Very low | Low–medium | Medium–high |
| Hides imperfections | Excellent | Good | Poor |
| Washability / durability | Low (better with washable formulas) | Good | Excellent |
| Moisture resistance | Poor | Moderate | Good |
| Typical NZ use | Ceilings, bedrooms, feature walls | Living areas, hallways, bedrooms | Kitchens, bathrooms, trims |
| DIY friendliness | Forgiving to apply | Forgiving to apply | Requires careful prep & application |
| Approximate cost (as a guide) | Similar across finishes; washable matts can cost slightly more | Mid-range | Similar to low-sheen; oil-based costs more |
Cost considerations
As a rough guide, the finish itself doesn't dramatically change the price per litre — you're more likely to see price differences based on brand tier, paint quality, and whether you choose water-based or oil-based. Premium washable matts and specialist bathroom semi-gloss products do tend to sit at the higher end of a brand's range.
You can compare options at Bunnings, Mitre 10, or PlaceMakers. Keep in mind that cheaper paint often means more coats and less durability — false economy in the long run.
Labour is typically the bigger cost factor. A professional painter will charge by the day or by the job, and the finish you choose can affect prep time (semi-gloss demands more surface filling and sanding).
NZ-specific considerations
New Zealand's climate varies enormously — from the humid subtropics of Northland to the cold, damp winters of the South Island. Moisture management matters:
- In high-humidity rooms (bathrooms, kitchens), always use a paint specifically formulated for wet areas, typically semi-gloss or a dedicated bathroom low-sheen. Check that the product meets the intent of NZ Building Code clause E3 (internal moisture).
- In older NZ homes with single glazing and limited insulation, condensation on walls is common. A washable low-sheen or semi-gloss is more forgiving than matt in these situations.
- The Healthy Homes Standards require rental properties to have adequate ventilation — good paint choices support (but don't replace) proper ventilation.
DIY or hire a professional?
Painting is one of the more DIY-friendly home improvement tasks — there's no restricted or licensed work involved for standard interior painting. That said, a professional painter will achieve a noticeably better finish, particularly with semi-gloss (which is unforgiving of poor prep and application technique).
If you're painting large areas, working at height, or dealing with significant surface repairs, it's worth getting a qualified tradesperson involved. You can find experienced local painters on tradedirectory.co.nz.
Safety note: Ensure good ventilation when painting indoors, especially with oil-based products. Check product safety data sheets for VOC levels and drying times.
Our recommendation
For most NZ homeowners, here's a practical starting point:
- Ceilings: Matt flat — always. It hides imperfections and there's no need for washability overhead.
- Living rooms and bedrooms: Low-sheen. It looks great, handles everyday marks, and suits most NZ wall conditions.
- Kitchens and bathrooms: Semi-gloss or a dedicated moisture-resistant low-sheen product.
- Trims, doors, skirtings: Semi-gloss — it's the industry standard for good reason.
- Feature walls or rooms with character: Matt can be stunning, just use a washable formula if the room sees foot traffic.
When in doubt, grab sample pots and test on your actual walls — sheen looks very different under different lighting conditions and against your furnishings.
