Refrigeration guys in Chch?

Anyone here based in Christchurch know anything about refrigeration? I've got an older F&P under bar fridge (1.8m x .9m x .6m) which is missing the remote unit, looking to get a compressor/condenser, or whatever I need to get it going.

Inside the fridge there's a fan and evaporator, two copper pipes leading outside the main unit have been cut off - i'm guessing I can get a compressor/condenser unit and have it braised up, gassed up and away I go?

Thanks
