Nobody confirmed if the matter has been settled out of court. The High Court has been approached for more information.
The civil proceeding before Justice Christian Whata started in May and was expected to continue until at least September.
The lawsuit focused on James Hardie's Harditex monolithic cladding system.
People suing the James Hardie group claimed the cement and fibre cladding system caused problems including damp, mould and rot in their houses.
Simon Hughes QC, a lawyer for the plaintiffs, told the court Harditex was not properly tested for New Zealand conditions.
But James Hardie said shoddy workmanship was to blame for many of the alleged problems.
Hodder previously told the court Harditex was introduced after appropriately designed and best practice testing.
"Properly installed, Harditex drains and dries well."
Harditex was withdrawn from the market in 2005.
