Any changes to KiwiSaver that could allow budding farmers to buy a herd of cows or flock of sheep would be a slippery slope according to one retirement fund provider. People who have been in KiwiSaver for three years can withdraw almost all the money to buy a first home, but they have to live in it. But Federated Farmers is applying pressure on the government to deliver on National's pre-election promise to unlock KiwiSaver so it can be used to buy stock, and first homes that wont be owner occupied. Agriculture Minister, Todd McCLay told Checkpoint he hopes to deliver on the promise. But not everyone thinks its a good idea. Founder of Koura KiwiSaver, Rupert Carlyon spoke to Lisa Owen.
