The National Party leader says plans to charge GST on KiwiSaver fees should be stopped.
The move is part of a new government bill imposing GST on financial services, and modelling suggests it could result in more than $100 billion less saved in KiwiSaver accounts by 2070.
Christopher Luxon told Morning Report it shouldn't go ahead.
Revenue Minister David Parker said the change is being made to get consistency of GST treatment across all investment services.
