Three protected names, different scales
- Canterbury: Canterbury is a broad registered GI on the eastern South Island. North Canterbury and Waipara Valley/Waipara are also registered names within this wider setting.
- North Canterbury: The registered GI includes the vineyard country around Christchurch and north toward Waipara. Its legal status dates from 29 June 2020; it is not simply an unregistered marketing name.
- Waipara and Waitaki: Waipara Valley is a local GI north of Christchurch, within North Canterbury geography. Waitaki Valley farther south has its own registered GI and is neither a Waipara subregion nor a Central Otago subregion.
