New Zealand's biggest off-site housing manufacturer, which owes creditors $17.5 million, received a $287,500 Government grant before Prime Minister John Key opened its Kumeu factory.
Jordan Williams, executive director of lobby group the Taxpayers Union, discovered the money was paid three years ago to eHome Global (NZ), now eHome NZ, in receivership.
He wants to know more about why that grant was given and how it was used.
The money came from the Ministry of Science and Innovation on December 5, 2012, because eHome had "a manufacturing process and construction techniques for conventional homes using panelised components", the ministry said.
