Hi Jordan,
The Actinidia Arguta Issai kiwi variety in which your refering is said to be native to areas of North China and even Siberia according to numerous sources. I think its fair to assess its USDA hardiness zones as recomended between zones 3 and 8. Because hardiness zones are determined by minimum winter temperatures, cooler areas of zone 9 that don't get to hot in summers, like the northern coastal areas on the West Coast, may also be applicable.
Hope that helps!
