One of the largest class action lawsuits in New Zealand's history was filed today.
The $200 million claim, against building giant James Hardie, alleges that faulty cladding was provided to more than 1000 homeowners, resulting in leaky buildings.
Litigation lawyer Adina Thorn says the allegation is that James Hardie made and supplied faulty HardieTex, Monotek and Titan board materials.
It was these products that were used to build thousands of properties around the country.
Ms Thorn says the claim is for losses suffered by the owners who have had extensive leaks, rot and mould throughout their homes.
Homeowner Mike Holmes, whose house was affected, says the faulty materials have set him back.
"I've got a young family, so it's a legacy you wanna leave your children for the future," he said.
The claim could take more than three years to go through the courts.
