The number of people signing up for KiwiSaver jumped in August and is now just short of 1.8 million.
KiwiSaver provider Tower Investments says almost 20,000 new members signed up in August, after a slump in growth in the wake of the Government's May budget.
Tower Investments chief executive officer Sam Stubbs says, if the latest sign-up rate continues, KiwiSaver numbers will reach two million in ten months.
He says the spike in membership could be due to employment growth due to improving business confidence as well as new hiring for the Rugby World Cup.
Mr Stubbs says the major issue with such strong growth is that many new KiwiSaver members will end up in default funds that are very conservative.
