The op shop at Hibiscus Presbyterian Church Orewa is on Centreway Road in Orewa, Rodney, rated 5.0 on Google.
A good op shop turns over stock constantly, so what's on the rails changes week to week and the best finds often go to whoever calls in most regularly. Donated goods are sorted by volunteers, which is why pricing tends to be low and simple rather than curated like a vintage store, and quality varies from item to item. Church-run shops in particular tend to put proceeds straight back into local causes, so a purchase does double duty as a small donation. Regulars know to bring cash for small buys, check back after a weekend when new donations have just been sorted, and not to expect a fixed range of sizes or styles on any given visit.
In Orewa, this op shop at Hibiscus Presbyterian Church is a chance to pick up a bargain while supporting the church's local work.
