Safety

Asbestos found

This can change development yield, consent pathway, purchase price, funding, construction cost, settlement timing, or legal risk. Treat it as a decision point, not background noise.

Due diligence / demolitionCriticalasbestosdemolitionhazardous materialWorkSafe

What it looks like

  • Suspect cladding, soffits, vinyl, textured coatings, pipe lagging, or other materials are found before or during demolition/refurbishment.
  • Workers stop because material may be asbestos-containing.

Likely causes

  • Older building materials
  • No pre-demolition survey
  • Hidden materials exposed during works
  • Renovation history

Immediate action

  1. 1Pause the affected decision or commitment until the issue is understood.
  2. 2Record the issue in the risk register with date, source, owner, and next action.
  3. 3Send the relevant documents to Competent asbestos assessor, Licensed asbestos removalist where required, Builder/demolition contractor and ask for written advice.
  4. 4Update feasibility, programme, budget, and decision register if cost, time, yield, consent, title, finance, or sales assumptions may change.

Step-by-step solution

  1. 1Define the problem in one sentence and identify which project decision it affects.
  2. 2Check the controlling documents: Asbestos survey, Removal plan, Clearance records, Demolition plan, and related project records.
  3. 3Ask the responsible professional to confirm whether the issue is real, minor, manageable, or project-changing.
  4. 4List the available options: redesign, renegotiate, seek consent, add cost allowance, change programme, change sales strategy, or abandon.
  5. 5Price and programme each option using the current feasibility model.
  6. 6Make a written decision with source references and approval from the developer or project owner.
  7. 7Notify affected parties such as lender, lawyer, consultants, builder, agent, buyer, or council when required.

What not to do

  • Do not rely on a seller, agent, or builder comment when a planner, lawyer, accountant, engineer, surveyor, valuer, lender, or council needs to confirm it.
  • Do not hide the issue from the feasibility just because the project looked profitable yesterday.
  • Do not waive due diligence, lodge consent, sign a contract, approve a variation, or promise settlement while the issue is unresolved.
  • Do not give legal, tax, finance, planning, engineering, or council advice to others unless a qualified professional has confirmed it.

Source / Where to check

Use before demolition, refurbishment, or disturbance of possible asbestos-containing material.

Use WorkSafe NZ for construction health and safety duties, risk management, and practical guidance for residential construction work.

Relevant professional advice

Planner, surveyor, architect, engineer, quantity surveyor, lawyer, accountant, lender, valuer, real estate agent, and other project specialists must confirm site-specific decisions.

Cost impact

High if licensed removal, clearance, programme delays, and disposal costs are required.

Programme impact

High because affected work must stop until safe process is confirmed.

Risk level

Critical
