Labour's leader is doubling down on his concern about the India-New Zealand free trade agreement's $33 billion Kiwi investment target. 

The party's finally agreed to support the FTA, but is warning businesses to proceed at their own risk. 

Chris Hipkins says the multi-billion-dollar target is unrealistic. 

He says down the line, it could affect businesses that redirect exports to India. 

"You've redirected product where you've developed a market - you could find that the constraints that have stopped you doing that until now are suddenly reimposed."
