Owen Campbell lives in Wellington, New Zealand, and coordinates finances for his shared flat. In this interview, he outlines his approach to bill splitting, communication, and learning from early mistakes. His story highlights the value of routine and open discussion.
In my current setup, I live with two other people in Wellington. I’m the main organiser for our flat’s finances. At the start of each month, I set up a document listing all our recurring bills, like rent, power, and internet. Each flatmate checks off when they’ve paid their share, and we use a group chat to send reminders or handle any new expenses. If someone is away for a while, we adjust the split for that month so no one overpays. The system isn’t fancy, but it keeps us organised.
The best part has been the sense of relief. Before this routine, we’d forget about a bill or argue over who paid what. Now, it’s clear and predictable. The hardest moments come when something unexpected happens, like a big repair. We have a rule: talk about costs openly as soon as they come up, so no one feels out of the loop. That’s helped us avoid resentment and keep things running smoothly.
Our main mistake was not agreeing on a process early enough. We used to split things on the fly, which led to confusion and sometimes double payments. Creating a shared document and regular check-ins solved most of our issues. It took some getting used to, but it’s worth it for the peace of mind.
If you’re just starting out, keep things as simple as possible. Agree on one way to track and pay bills, and make it part of your regular routine. Don’t let embarrassment stop you from asking about payments or raising concerns. The earlier you talk, the easier it is to sort out any issues. Use reminders — a group chat is often enough.
I’ve realised that routines are more important than any particular tool. Once everyone expects regular updates and clear communication, managing money becomes much less stressful. The skills I’ve built through this process have helped me at work and in other group situations, too. It’s about building habits that support fairness and trust.
