None of this means Auckland is losing its status, it still holds more million-dollar suburbs than the rest of the country combined. But the phrase that once belonged to it is no longer Auckland's alone. The million-dollar suburb has become a national feature, turning up in Cromwell, in Napier, on the Kāpiti Coast, and the next wave of them will keep appearing in the places that were, until recently, comfortably affordable.
Whether the line keeps rising to meet those places depends on the same forces that carried it there, steady demand, limited supply, and prices with room left to climb. If they hold, the map of New Zealand's most expensive suburbs will keep spreading out from the two big cities that used to define it.
Methodology
The analysis uses REINZ median sale prices at suburb level, measured over rolling twelve-month periods to June each year. We included only suburbs with at least 30 sales in the past year, since a median built on a few transactions can swing on a single sale.
To count as approaching $1 million, a suburb's current median had to sit above its 2021 level. This matters: several suburbs, particularly in Wellington, are rising fast off the post-boom trough but remain below their 2021 prices. They are recovering lost ground, not breaking new ground, and counting them would overstate how far the million-dollar line has spread.
The "months to $1 million" figure projects each suburb's three-year growth rate forward to the mark. It assumes recent pace continues, so it is best read as how close a suburb sits to the line, not a date it will cross. Finally, we measured growth over three years, recent enough to reflect current conditions without the 2021 peak distorting the result.
