With NZ’s leaky building legacy costing billions and unfortunately still going on with many new builds leaking even though they have been signed off by council, spotting weathertightness red flags early is critical, especially in Auckland and Waikato, where rain and humidity amplify risks.  This detailed overview includes more signs, causes, and fixes to empower home and commercial property owners.

1.  Water Stains or Discolouration: Indicates penetration; check ceilings after dry spells too. 

2.  Mould or Musty Smells: From chronic damp, affecting 30% of NZ homes.

3.  Cracks in Cladding: Common in monolithic types, but also prevalent in timber weatherboard and fibre cement claddings allowing moisture entry.

4.  Peeling Paint or Blistering: Signals trapped moisture; often from poor preparation or trapped moisture.

5.  Unconsented Work or Flood Risks: Understanding the properties history and hidden risks, verify records to avoid legal pitfalls and costly remediation or litigation.

6.  Poor Ventilation/Insulation: Causes condensation; upgrade to meet 2025 standards.

New builds can and do fail too if not inspected and repaired or maintained correctly.
