How Much Do You Need to Retire in New Zealand?

"How much do I need to retire?" is probably the single most common question we get from clients over 45, and the honest answer is that it depends enormously on what kind of retirement you want. A couple who are happy pottering around the garden, cooking at home, and taking the occasional domestic holiday need far less than a couple who want to travel overseas every year and eat out twice a week. But we can absolutely put some useful numbers around it, and having a target - even a rough one - is infinitely better than hoping it all works out.

What the Research Says About Retirement Costs

The Retirement Commission publishes expenditure guidelines that give us a solid starting point. For a single person, a "no frills" retirement costs roughly $31,000 per year, while a "comfortable" retirement runs closer to $51,000. For couples, those figures are approximately $45,000 and $69,000 respectively. These numbers assume you own your home outright with no mortgage, which is a critical detail. If you are renting in retirement, you can add $15,000 to $30,000 per year depending on where you live - Auckland rents alone could push a couple's annual costs well above $90,000.

These are also averages across the country. Living costs in Invercargill are quite different from living costs in central Auckland, so take them as a guide rather than gospel. The key point is that "comfortable" does not mean extravagant - it means being able to afford reasonable healthcare, some travel, and the ability to replace your car when it dies without a financial crisis.

NZ Super as Your Foundation

New Zealand Superannuation provides a meaningful base income that many countries do not offer. A single person living alone receives roughly $27,000 per year after tax, while a couple gets around $41,500. This is not means-tested, so you receive it regardless of your other income or assets (though it is taxable income). NZ Super alone covers a basic lifestyle for most people, but the gap between "basic" and "comfortable" is what your personal savings need to bridge.

For a couple targeting $69,000 per year in retirement spending, NZ Super covers about $41,500, leaving an annual shortfall of $27,500. Over a 25-year retirement, that adds up to $687,500 in today's dollars - though investment returns on your savings will do some of the heavy lifting along the way, so the lump sum you need at retirement is somewhat less than that raw figure.

The 4% Rule and Why It Needs Adjusting for NZ

You may have heard of the "4% rule" - the idea that you can withdraw 4% of your retirement savings each year and your money should last roughly 30 years. The rule comes from US research and assumes a portfolio split between shares and bonds earning US-style returns. In a New Zealand context, where conservative investments have historically returned a bit less, most financial advisers suggest using 3% to 3.5% as a safer withdrawal rate.

Using a 3.5% withdrawal rate, a couple needing $27,500 per year from savings (on top of NZ Super) would need roughly $785,000 saved at retirement. A single person targeting $24,000 per year above Super would need around $685,000. These are ballpark figures, but they give you something concrete to aim at.

The Variables That Can Blow Your Budget

Health costs are the big unknown. New Zealand's public health system covers major medical needs, but dental work, optometry, hearing aids, and elective procedures can add up quickly. A single dental crown can cost $1,500 to $2,500, and as you age, these expenses tend to increase rather than decrease. Budget somewhere between $5,000 and $15,000 per year for health-related costs, with the higher end becoming more realistic in your late 70s and beyond.

Aged residential care is the other wildcard. Rest home fees run from around $1,200 to $2,000 per week for standard care, and significantly more for hospital-level or dementia care. The government provides a subsidy if your assets fall below certain thresholds, but many retirees end up paying privately for at least some period. A two-year rest home stay at $1,500 per week would cost $156,000 - enough to seriously dent most retirement savings.

Longevity itself is a planning challenge. A 65-year-old New Zealander can expect to live to roughly 84-86 on average, but averages hide wide variation. Planning for 25 to 30 years of retirement is sensible, and if your family tends to live into their 90s, plan accordingly.

Where KiwiSaver Fits In

KiwiSaver is the primary retirement savings vehicle for most New Zealanders, but average balances at 65 are still quite low - typically in the $50,000 to $80,000 range. This reflects the fact that KiwiSaver has only been around since 2007, so nobody has had a full working lifetime of contributions yet. Younger Kiwis who have been contributing since their 20s should end up with substantially larger balances, but anyone over 50 today probably needs to be thinking about additional savings beyond KiwiSaver.

If you are in your 30s and contributing 3% plus your employer's 3%, you are on a reasonable track but could do much better by increasing to 6% or 8%. Someone starting at 30 with combined contributions of 6% on average earnings could realistically accumulate $400,000 or more by 65, depending on fund performance. If you are in your 50s and feeling behind, increasing your contribution rate and reviewing your fund type are the two most impactful things you can do. Moving from a conservative fund to a balanced or growth fund - if you still have 10 or more years until retirement - could make a meaningful difference to your final balance.

What You Can Actually Do About It

The single most valuable thing is to calculate your personal number. Work out what you want to spend in retirement, subtract NZ Super, and figure out how much savings you need to fill the gap at a 3.5% withdrawal rate. Then compare that to where you are now and what your KiwiSaver is projected to reach. If there is a gap, you have options: increase KiwiSaver contributions, save or invest outside KiwiSaver, plan to work a few extra years, or adjust your retirement expectations. None of these are fun conversations, but having them at 50 is a lot more productive than having them at 64.
