I’m not sure why New Zealand Whey became Kaha Nutrition?? Since the change I've noticed a few differences. First New Zealand Whey sweetened with Stevia. Kaha sweetens with Monk fruit which is slightly sweeter than Stevia but like Stevia is a healthy sweetening choice. Secondly the Kaha bottles don't seem packed as high the New Zealand Whey bottles were . I continue to buy as I still consider this a great product with only a few healthy ingredients.
