Joint or separate? How dual-income NZ households really run their money in 2026

Should you keep your money joint, separate, or somewhere in between? After thousands of onboarding calls and customer interviews with NZ households, SortMe Founder & CEO Carl Thompson thinks that's the wrong question. The real one is how two incomes should actually flow through one household — where each pay lands, how the bills get paid, where each partner gets some autonomy, and how anyone ends up with a single screen showing the whole picture. To dig into the relationship side of it, this episode brings in Erika Palmer, Founder & CEO of Cupla — the shared-calendar app used by half a million couples — who's watched the same pattern play out across hundreds of thousands of relationships. "The couples who plan together don't just stay together — they like each other more," she says. This episode walks through the three money frameworks NZ couples drift into, the four-bucket setup that actually scales for the next 20 years, and exactly how to set it up so both partners are looking at the same screen.

Contention enters when the person carrying the load feels their effort isn't seen.
