Between 2020 and 2024, New Zealanders aged 60-64 added nearly 300,000 new income sources. That's not 300,000 people. That's 300,000 additional streams of taxable income flowing to people in a five-year age bracket who are supposed to be winding down, not ramping up.

Here's the tension: this is the age when most Kiwis are meant to be simplifying their working lives, maybe going part-time, preparing for retirement at 65. Instead, the data shows them adding income sources at a rate of roughly 75,000 per year since 2020.

In 2020, this age group had 2.27 million income sources. By 2024, that figure hit 2.56 million. The growth rate is accelerating: the jump from 2023 to 2024 alone accounts for 65,000 new income streams, the second-largest annual increase in the dataset's 24-year history.

What does this actually mean? It means a 62-year-old tradesman taking on weekend consulting work. A 63-year-old retail manager picking up a second part-time role. A 61-year-old nurse doing agency shifts on top of their regular hours. It means people who thought they'd be scaling back are instead doubling down.

The most likely explanation: they can't afford not to. KiwiSaver balances that looked adequate five years ago don't stretch as far when your power bill's up 30% and your rates keep climbing. Mortgages that were supposed to be paid off by now aren't. Adult kids who were meant to have moved out are back home, or asking for help with their own housing deposits.

This isn't about ambition or boredom. The data doesn't capture motivation, but it captures behaviour, and the behaviour is clear: New Zealand's early-sixties cohort is working harder and juggling more income sources than any comparable group in the past two decades.

Compare this to 2010, when the same age bracket had just 1.74 million income sources. That's an increase of 820,000 sources in 14 years. The slope of that line has been getting steeper, not flatter, as this group approaches what's supposed to be the finish line.

The policy implications are obvious but uncomfortable. If people in their early sixties can't afford to slow down, what does that say about retirement at 65? What does it say about the adequacy of NZ Super as a sole income source? What does it say about the financial pressure facing the generation that's meant to be first in line for a dignified exit from the workforce?

The data doesn't answer those questions. But it's asking them louder every year. (Source: Stats NZ, taxable-income-sources)
