Google it. It all depends what kind of seed potato you can buy there. Try Bunnings or produce places.

Stumbled in and grew some Royal Blue in container. Tipped out this week as I want to start some Kipfler. NO SPUDS! Now realise I did 2 things wrong 1: planted in November (= lots of lovely foliage) 2: Used sprouting (table) spuds from Greengrocer. This time I'm doing it right! (I hope). Got Seed Spuds (Kipfler like) "Pink Fur Apple". Made a planting medium following research. Planting early July. Hope springs eternal!

You are in Temperate NZ zone so look up Potatoes for that zone - use the Vegetables and Herbs tab

Are you looking for SWEET potatoes or regular potatoes ..... I think your climate is better suited for Sweet potatoes -- they are different (different families) and therefore have different instructions: The ideal soil temperature range for planting potatoes is 45 to 50 degrees Fahrenheit (7 to 10 degrees Celsius). After planting, the ideal temperature for growing potatoes is 60 to 70 degrees Fahrenheit (16 to 21 degrees Celsius). Potatoes do best in fertile, well-drained soils. However, potatoes will grow in many types of soils. Soils that are poorly drained tend to produce poorly shaped potatoes and tuber rot. Potatoes do well across a wide range of pH, but prefer slightly acidic soils; a soil pH of 5.3 to 6.0 is typical for potato production. If your soil is more acidic than this, mixing in wood ash will help raise the pH and make your soil more alkaline. Sweet potatoes (Ipomoea batatas) are close cousins of morning glory and only distantly related to traditional potatoes. They are tender, so must be protected from frost, and like heat, full sun and regular watering. They crop best at temperatures of 21–26°C (70–80°F) PLEASE CLARIFY which type of potato.
