Lead Paint in Wellington Homes: What You Need to Know
If your Wellington home was built or painted before 1980, there's a high probability it contains lead-based paint. Lead was a common paint ingredient until banned for residential use in New Zealand in 1979. Today, lead paint poses serious health risks — particularly to children — and requires careful management.
As licensed Registered Master Painters with certified lead paint removal training, we've safely removed lead paint from hundreds of Wellington properties. This guide covers testing, regulations, safe removal methods, and costs.
Why Lead Paint is Dangerous
Health Risks
Lead Toxicity:
Lead is a neurotoxin that accumulates in the body, particularly affecting:
- Children under 6 (developmental damage, learning difficulties)
- Pregnant women (affects foetal development)
- Adults (cardiovascular, kidney, reproductive issues)
Exposure Pathways:
- Dust: Sanding or scraping creates toxic dust (primary risk)
- Paint chips: Peeling paint chips ingested by young children
- Fumes: Burning or heat stripping releases toxic vapours
- Soil contamination: Decades of paint chips around house perimeter
The Critical Point:
Intact lead paint that's well-maintained poses minimal risk. The danger comes when lead paint deteriorates, is disturbed during renovations, or is removed improperly.
Wellington's Lead Paint Reality
Pre-1980 Housing Stock:
Wellington's extensive heritage suburbs — Thorndon, Mt Victoria, Kelburn, Aro Valley, Mt Cook — contain thousands of pre-1940 villas. Most contain lead paint on original surfaces.
Common Lead Paint Locations:
- Exterior weatherboards (highest concentration)
- Window frames and sills (very high lead content)
- Interior doors and architraves
- Ceilings (older homes)
- Balustrades and railings
New Zealand Lead Paint Regulations
Legal Framework
Health and Safety at Work Act 2015:
Controls workplace exposure to lead. Professional painters and renovators must comply with exposure standards.
Hazardous Substances Regulations:
Governs lead paint removal, disposal, and containment.
Building Code and Consent:
Some councils require building consent for lead paint removal work, particularly on heritage properties.
Exposure Standards
Workplace Exposure Limits:
- Blood lead level action: 10 μg/dL
- Remove from exposure: 30 μg/dL
- Air lead concentration: 0.05 mg/m³ (8-hour time-weighted average)
Professional Requirements:
Licensed painters conducting lead removal must:
- Use appropriate safety equipment
- Implement containment systems
- Monitor worker exposure
- Provide health surveillance
- Maintain compliance records
DIY Restrictions
Important: While not illegal for homeowners to remove lead paint from their own properties, WorkSafe strongly discourages DIY lead removal and mandates professional removal for commercial/rental properties.
Why Professional Removal Matters:
- Correct containment prevents family exposure
- Proper disposal protects environment
- Experience minimises risk
- Compliance with best practice standards
Lead Paint Testing
When Testing is Essential
Before Any Work:
Test before sanding, scraping, demolition, or renovation of pre-1980 surfaces. Never assume — test to confirm.
Before Purchasing:
Property buyers should request lead paint testing during building inspections for pre-1980 homes.
If Children Present:
Families with young children should test deteriorating paint immediately.
Testing Methods
1. DIY Test Kits ($15-30 per test)
How They Work:
Swab kits contain chemicals that turn pink/red when lead present.
Pros:
- Immediate results
- Inexpensive
- No lab wait time
Cons:
- Only indicate presence/absence (not concentration)
- False positives possible
- Multiple tests needed for different surfaces/layers
Recommended Use:
Quick screening before renovation planning.
2. XRF Testing ($200-400)
How It Works:
X-ray fluorescence analyser measures lead content instantly without damaging surface.
Pros:
- Non-destructive
- Instant results
- Measures concentration
- Tests through multiple layers
Cons:
- Professional equipment required
- Higher cost
- Not widely available
Recommended Use:
Professional assessment for major projects.
3. Laboratory Testing ($50-100 per sample)
How It Works:
Paint chip samples sent to accredited lab for analysis.
Pros:
- Most accurate method
- Quantifies lead concentration
- Legally defensible results
Cons:
- Requires surface damage (chip removal)
- 1-2 week turnaround
- Higher cost for multiple samples
Recommended Use:
Definitive testing for heritage, legal, or high-risk situations.

Safe Lead Paint Removal Methods
1. Chemical Stripping (Preferred Method)
Why It's Safest:
- Minimal dust creation
- No heat/fumes
- Controlled removal
- Paste contains lead as it dissolves
Process:
- Apply thick coating of lead-safe paint stripper
- Cover with plastic film (prevents drying)
- Allow 12-24 hours to work
- Scrape off dissolved paint into sealed containers
- Neutralise surface
- HEPA vacuum all residue
Best For:
- Detailed mouldings
- Heritage weatherboards
- Window frames
- Interior joinery
Cost: $80-150 per m² (includes containment, disposal)
2. Wet Sanding (Acceptable with Precautions)
Safe Approach:
- Keep surface continuously wet (suppresses dust)
- Use HEPA-filtered sanders only
- Full containment system
- Respirator protection
Limitations:
- Still creates some lead dust
- Difficult on complex profiles
- Requires extensive cleanup
Best For:
- Simple flat surfaces
- When chemical stripping impractical
Cost: $60-100 per m² (includes containment, disposal)
NEVER Use These Methods for Lead Paint
❌ Dry Sanding/Scraping:
Creates massive lead dust clouds. Extremely dangerous.
❌ Heat Guns/Torches:
Vaporises lead, creating toxic fumes. Risk of fire.
❌ Sandblasting:
Disperses lead dust widely. Contaminates surrounding area.
❌ Power Washing:
Spreads lead chips and dust. Contaminates soil and gardens.

Professional lead removal protects your family's health, complies with regulations, and prevents environmental contamination.
DIY Lead Paint Removal: Our Strong Caution
WorkSafe Recommendation:
Engage professional lead removal specialists rather than DIY.
If You Insist on DIY:
Absolute Requirements:
- Confirm no children under 6 in household
- Confirm no pregnant women present
- Full P3 respirator (not dust mask)
- Disposable coveralls
- Proper containment (plastic sheeting, sealing)
- HEPA vacuum (not standard vacuum!)
- Chemical stripping only (no sanding, heat, scraping)
- Shower immediately after, dispose of coveralls
- Certified disposal of waste
Realistic Assessment:
DIY lead removal saves money but risks family health. Most homeowners lack equipment, training, and experience to do it safely.
Our Recommendation:
Pay for professional removal. Your family's health is worth far more than cost savings.
Protecting Your Family During Removal
Recommended Precautions:
1. Vacate During Work:
Move family (especially children, pregnant women) to alternative accommodation during removal and initial cleanup.
2. Isolate Work Area:
Seal interior work areas completely. No access by family members.
3. Post-Work Cleaning:
Professional cleanup and verification before family returns.
4. Test After Work:
Dust wipe testing confirms successful decontamination.
What Happens After Lead Paint Removal?
Immediate Priming Essential:
Stripped surfaces must be primed within 24-48 hours. Bare timber absorbs moisture and deteriorates rapidly.
Lead-Free Paint System:
Use modern lead-free paints for all new coatings. We recommend Resene premium acrylics formulated for NZ conditions.
Ongoing Monitoring:
If lead paint remains in other areas, monitor condition and manage deterioration proactively.
