How much do you actually need to retire?
Before the number, there's a better question: what does the retirement you're picturing actually look like? Regular travel and eating out whenever you like is a genuinely different number from a quiet life close to home - and “how much do I need” only has a real answer once you know which one you're aiming at.
What it actually costs - and why today's number isn't the right one
Whatever lifestyle you land on, it costs more by the time you get there than it does today. Prices rise every year between now and retirement, so a weekly figure that looks comfortable in today's dollars will buy less by the time you're actually living on it. This is the single most common thing people underestimate when they try to work out “how much” in their head rather than running it through a calculator.
Research from Massey University's retirement expenditure guidelines shows the gap between a genuinely no-frills retirement and a comfortable one is bigger than most people expect - bigger, usually, than the gap people assume when they picture “modest” versus “comfortable” in the abstract. That gap is exactly why “what do I want” has to come before “how much do I need” - the number only means something once it's attached to an actual lifestyle.
Will NZ Super be enough if you retire at 60?
Worth being direct about this one: NZ Super doesn't start until age 65. Retire at 60 and you're covering five full years with no NZ Super income at all, on top of whatever gap exists between NZ Super and the lifestyle you actually want from 65 onward. That's a materially different planning problem from “will NZ Super be enough” - it's “how do I fund five years before NZ Super even starts.”
Saving is safe - getting you there safely is a different question
Saving steadily is genuinely safe, and where it can realistically reach the retirement you want, it's a great way to plan for it. But “safe” describes the saving, not the outcome - those are two different claims, and it's worth being clear-eyed about which one you're actually relying on. At realistic rates of return, saving alone often doesn't close the gap for anything beyond a genuinely no-frills retirement - the size of most people's gap, weighed against what saving typically returns, means it's unlikely to get anywhere near a more comfortable target on its own. The younger you are, the more that changes, since more years gives it more room to compound. With fewer years left until retirement, that gap matters more, not less - which is exactly why it's worth calculating what saving alone actually brings you, rather than assuming that because it's safe, it's sufficient.
That's worth knowing now, while there's still time to do something about it either way - isn't it?
How to actually work out your number
The method is simple even though the arithmetic isn't something to do in your head: start with the weekly income you want in retirement, in today's dollars. Adjust that for inflation between now and the age you plan to retire. Multiply by how many years you expect to be drawing on it. That gives you the nest egg figure your plan is actually aiming at.

FAQ
It depends on the lifestyle you want, adjusted for inflation between now and retirement, over however many years you'll be drawing on it. There's no single national figure that applies to everyone - try My Nest Egg Calculator, which works it out from your own answers.
"Comfortable" means something different to everyone, which is exactly why the research shows a wide gap between a no-frills retirement and a genuinely comfortable one. The useful starting point is naming what comfortable actually looks like for you, then working the number backward from there.
NZ Super doesn't begin until 65, so retiring at 60 means funding five years with no NZ Super at all - a different and bigger question than whether NZ Super alone is enough from 65 onward.
Start with your desired weekly income in today's dollars, adjust it for inflation to the age you plan to retire, then multiply by your expected years in retirement. Try My Nest Egg Calculator, which does this calculation on your actual numbers.
