Canterbury District Health Board is seeking legal advice about how Mainzeal's receivership might affect work the company is doing for the board.
Mainzeal, the country's third largest construction company, went into receivership on Wednesday, leaving 400 employees and sub contractors in limbo.
The company has several redevelopment contracts with the board, including one worth more than $150 million for earthquake repairs in hospitals and other facilities.
Three other contracts worth about $24 million are for upgrades to other buildings.
DHB chief executive David Meates said he hopes to have a better understanding about the future of these projects by the end of the month.
