Latest figures show the number of KiwiSaver members making such withdrawals increased substantially from 1570 people in October 2022, to 2800 people in October 2023.
The amount of money withdrawn from KiwiSaver due to financial hardship doubled, from $10.3 million in October 2022 to $21.5m in October 2023.
IRD said the five regions with the most funds withdrawn for this reason were (respectively): Auckland, Canterbury, Waikato, Wellington and Bay of Plenty.
In August, a Retirement Commission survey found 55 per cent of New Zealanders reported being in financial difficulty, up 17 per cent since 2021. Women, Māori and Pacific peoples were affected the most.
Those results showed people were having trouble putting away savings, which would result in long-term consequences for their future financial well-being, Retirement Commission personal finance lead Tom Hartmann said.
Money taken from KiwiSaver accounts to purchase a first home also showed a significant increase in the latest IRD data, going from $77.7m in October 2022, to $104.7m in October 2023.
In March, The Financial Markets Authority said total membership in KiwiSaver had increased 2.7 per cent during the past year to 3.25m people, with $93.7 billion wrapped up in the scheme.
