There are purple patches on the light-brown skin. Inside, the potato has off-white flesh with purple flushes in it.
These are waxy potatoes.
They are good for oven-baked potato wedges or chips (aka French Fries in North America.)
Whataroa Potatoes were developed in New Zealand.
Named after Whatarora, New Zealand.
