Painting Cost vs Plastering Cost in NZ

• Painting only - Surfaces are smooth, intact, and just need a colour refresh or protective coating - Master Painters NZ sets workmanship standards for this. See interior painting costs for what a standard repaint runs.
• Plastering only - New walls need GIB stopping, or existing walls have significant damage.
• Both - Most renovation projects. Plaster repairs are done first, followed by painting over the repaired surface.

Many NZ trade businesses offer both services. Some painters do minor plaster repairs; major plastering work needs a specialist.

Plastering is a more specialised trade with higher material and labour costs:

• Skilled trade - Plastering requires more training and precision than painting.
• Material costs - Plaster, mesh, primers, and texture coatings are more expensive than paint.
• Multiple stages - Plastering requires multiple coats with drying time between each.
• Clean-up - Plastering is messier and more labour-intensive to clean up.

For a detailed breakdown of what painting alone costs, see our guide to painting costs in NZ.

You only need painting if:

• Walls are in good condition with no visible damage
• There are no cracks, holes, or uneven surfaces
• The existing paint is sound and not peeling or flaking

You need plastering before painting if:

• Walls have cracks, dents, or water damage
• New gib or plasterboard has been installed
• Surfaces are uneven or have a rough, poorly finished texture

You need both plastering and painting if:

• You're renovating a room or repairing storm or water damage
• Surfaces need levelling or patching before a finish coat
• You want a smooth, high-quality result that lasts

In most cases, plastering is the preparation work, and painting is the finishing step. If you're unsure what your walls need, use our painting quote example to get an estimate based on your situation.

If your walls aren't in good condition, plastering is often required before any paint goes on. This adds to the total project cost - and it's one of the most common reasons a painting quote comes in higher than expected.

• Extra labour and time - Plastering adds 1–3 days to a project depending on the area and condition of the walls. Each coat needs drying time before the next step.
• Additional materials - Filler, plaster, mesh tape, and primer all add to the materials bill on top of paint.
• Poor surfaces show through paint - Cracks, dents, and uneven patches are more visible after painting, not less. Skipping prep leads to a finish that looks worse than the original.
• Rework is more expensive - Fixing defects after painting means stripping, re-plastering, and repainting - often costing more than doing it properly the first time.

Worth knowing: A large portion of a "painting quote" can actually be surface preparation, not just painting. If a quote seems high, ask for a breakdown - you may find that most of the cost is in getting the walls ready.

If you want an accurate estimate, you need to include both preparation and painting work. Try our quoting tool to see the full picture.

Here's what a typical 3-bedroom house repaint looks like when both plastering and painting are required:

In this example, plastering adds roughly 27% to the total cost. In older homes or properties with water damage, that figure can climb to 40% or more. For painting-only pricing by surface area, see our cost per m² guide.

Key takeaway: The plastering work can make up a significant portion of the total cost, especially in older homes or damaged surfaces. When budgeting for a repaint, always factor in the condition of your walls - not just the painting itself.
