Higher contributions, lower take-home pay — what brokers need to know
National has announced a package that would make KiwiSaver compulsory, lift combined contributions to 12% by 2032, enrol newborns with a $1,500 kickstart, and extend employer contributions to workers over 65 and those on paid parental leave.
For mortgage advisers, the implication is immediate — higher contributions mean lower take-home pay, directly affecting borrowing capacity and serviceability.
Prime Minister Christopher Luxon sought cross-party support for the changes, arguing the policy was common sense regardless of political allegiance.
"There are things that we can do to improve the programme and make it even stronger, so that actually, irrespective of your background or your circumstances, everyone's got an opportunity to build wealth over time," he told Morning Report.
The Financial Services Council welcomed the package, saying KiwiSaver settings needed to reflect how people actually live — taking time out of paid work, having children, and working longer.
NZX acting chief executive Graham Law was similarly supportive, arguing that "lifting participation and contribution rates will build large pools of long-term capital, improve market liquidity and financial resilience for New Zealanders."
That market enthusiasm, however, is not universally shared by those focused on household finances.
The affordability question brokers will hear
The welcome from markets and industry bodies sits alongside pointed concern from providers about what compulsion means for lower-income workers. Simplicity chief economist Shamubeel Eaqub told RNZ the bottom 60% of income earners would struggle with reduced take-home pay.
"For the bottom 60% of incomes, they are going to struggle if they have less take-home pay," Eaqub said.
Koura Wealth founder Rupert Carlyon — who has also warned about KiwiSaver volatility affecting first-home deposits — raised the pace of the increase as a concern.
"If you think about people who are today paying 7%, if we're going to go to 12% over the next few years, that's an extra 5% of salary, potentially. That's going to have to come from somewhere," Carlyon said.
Kernel founder Dean Anderson was more direct about the first-home buyer cohort: "If you're on a low income, dollars in hand matters most. Especially if they have any high interest personal debt. Losing 10% to 12% KiwiSaver is a nice-to-have, but not practical."
Employers, total remuneration, and the wage question
Business leaders warned that the extra employer contribution cost may not simply be absorbed — it may be offset against wages, RNZ reported.
BusinessNZ economist John Cask said plainly: "There's no such thing as a free lunch."
Former National leader and Auckland Business Chamber chief executive Simon Bridges acknowledged the long-term logic while flagging the near-term pressure: "12% is high and that does create real issues that shouldn't be underplayed for individuals, self-employed, small and medium businesses."
Tribe Recruitment's chief executive Bruce Pilbrow noted smaller businesses may shift to total remuneration packages — where the KiwiSaver contribution comes out of an employee's total pay rather than on top of it — a practice Eaqub said should be banned as it effectively reduces take-home pay rather than adding to savings.
On the positive side, a larger and more universal KiwiSaver scheme would over time mean more first-home buyers with meaningful deposits — a structural tailwind for the mortgage market that brokers are well-placed to benefit from.
The changes are costed at around $300 million a year and would require National to be re-elected in November. With a cross-party momentum building — NZ First already has a comparable policy — KiwiSaver is shaping up as one of the defining financial policy debates of the campaign, and one that clients will be asking their advisers about.
