Tinkering with KiwiSaver and offering new ways of spending the money risks diluting the plan designed to help with retirement, says Massey's Claire Matthews.
Opinion
It is unfortunate to see NZ First suggesting significant changes to KiwiSaver as part of its policy platform for the general election.
A clear message from the public has been that changing KiwiSaver creates a level of ongoing uncertainty, discouraging some people from joining and making others resentful of their required membership.
The suggested changes should not be supported for that reason alone.
Nevertheless, we should also consider the potential value of the specific changes that have been suggested.
Unfortunately the NZ First policy has a similar flaw to the Labour Party's KiwiSaver policy in trying to achieve multiple objectives.
The NZ First policy is arguably worse in that it moves away from the original purpose of retirement savings by trying to turn KiwiSaver into a general-purpose savings vehicle.
What's next - allowing funds to be withdrawn to pay for medical expenses or to establish a business?
KiwiSaver was established to help New Zealanders save for their retirement.
It was a response to the recognition that the standard of living available to someone relying solely on NZ Superannuation in retirement is marginal, and growing concerns about the affordability of NZ Superannuation given the growth in the number of retired New Zealanders.
We have already had some dilution of this focus, with the inclusion of a first home withdrawal benefit.
However, if this is done early enough in a person's membership the long-term effect is likely to be negligible - and there can be retirement related benefits from home ownership.
The NZ First policy goes much further by allowing withdrawals for education and a home, where the education can be for the member or someone else in their family.
A scenario where a KiwiSaver member gets to retirement with almost nothing in their KiwiSaver account is very easy to imagine.
For example, making withdrawals over their lifetime to fund their own education, the purchase of their first home, the education of their children, re-education for themselves due to changes in the job market and then education of their grandchildren, would leave little at retirement.
It is worth noting that the information on the NZ First policy is not clear on whether home purchase withdrawals are limited to their first home, or any home - the latter would further worsen this scenario.
Over time, better returns can usually be achieved by investing in shares.
However, this requires a long-term focus, which allows the short-term volatility to be tolerated.
Allowing withdrawals earlier than retirement, as suggested in the NZ First policy, moves the focus to a short-term horizon.
This would also have an impact on investment choices, with a preference for more conservative, less volatile investments which are likely to result in lower returns.
This would cause further deterioration in the situation at retirement.
Solutions to the concerns NZ First is seeking to address with its KiwiSaver policy should be sought, but not through KiwiSaver.
If NZ First is concerned about the cost of student loans, perhaps they should consider extending the availability of student allowances.
Concerns about a savings culture would be better addressed by improving financial literacy so that New Zealanders can have a better understanding of financial matters and take control of their financial situations.
