Monopoly Watch, a public policy group established to examine New Zealand's supermarket industry, says the failure of the online grocery start-up Supie shows just how tightly locked the sector is.
The independent Auckland-based supermarket launched in 2021 to try and bring more competition into the market.
Monopoly Watch spokesperson and Two Degrees founder, Tex Edwards, says what's happened should send a clear signal to policy makers that the market needs further intervention.
Edwards spoke to Ingrid Hipkiss.
