Law firms are registering interest for legal action from building owners worried they might have combustible cladding on their high-rises, but who have not been identified on any official list.
Combustible aluminium composite cladding and insulation helped fuel the Grenfell fire in London that killed 72 people in 2017.
Similar legal action's being taken in Australia and Britain.
Polly Pope of law firm Russell McVeagh is registering interest in a cladding class action to replace cladding on New Zealand high-rises.
She spoke to Phil Pennington.
