Two people have been arrested in connection with a burglary at Trelise Cooper's Epsom store.
A man, aged 41, has been charged with burglary and a woman, aged 45, has been charged with receiving stolen property.
In October, Dame Trelise Cooper's Auckland showroom was targeted by thieves who made off with more than 1500 garments.
The stolen clothing was estimated to be worth just under $1 million - two seasons' worth of new sample clothing.
Police say a "significant" amount of this clothing has been returned since the arrest.
Both of the people charged will appear in the Auckland District Court on Friday, and police say they cannot rule out further charges.
