Our NZ Whey Protein Isolate is sourced in New Zealand from Grass Fed Dairy Cows that graze on pastures all year round. It is processed through cross flow micro-filtration and ultra-filtration to enable the protein to remain undenatured.

The flavoured varieties are made with Organic Flavours & Natural Sweeteners making it tasty and ideal for those who want to enjoy a healthy protein shake or as a pre and post workout supplement. The facts are:

    Clean, not too sweet, and no side effects

    Posted by on 04 Apr 2017

    I had stopped drinking whey protein because I couldn't find one that wasn't overloaded with flavour and sweeteners.

    I am also sensitive to dairy (gives me sinus problems amongst other things). I was getting side effects from other whey proteins but this one seems to be fine.

    I got the mixed sampler pack and my favourite flavours were vanilla and cacao.

    NZ WPI - Amazing

    Posted by on 09 Mar 2017

    I've been drinking protein powders for pre and post gym and for meal replacements for the past 10 years and I find NZ WPI to be the best! It mixes easily with water. It tastes great and has a high protein content per serving. With no added fillers or nasties it's perfect for my post workout drink. Add a good price for this high quality delicious WPI and you have a five star rating. You can't go wrong, highly recommend it!

    Seriously so incredibly tasty and no nasties. I used to hate protein shakes but now I look forward to them. Delivery is fast and easy. Can't say a single bad thing about it.

    NZ WPI

    Posted by on 09 Feb 2017

    I have been having this product on an almost daily basis for breakfast for the last 5 years. It is a good start to the day. I have the natural powder with Almond Milk, banana, chia seeds and honey - delicious. I love it so much I take it away with me on holidays otherwise my day just doesn't feel the same. Recommend this to everyone whether it be for training or losing weight.

    This is a good product that the contents can be trusted not to have fillers or added sugars. The pack bundle is great as I have it for breakfast so it blends well. The delivery is good and the website is easy access

    Easy on the belly

    Posted by on 11 Nov 2016

    I use this protein every morning in my shakes. I suffer from digestive issues and find it hard to find a protein powder gentle enough. This protein is great for gut aswell as being delicious enough to mix with just plain water!! Love it.

    Great taste, easy digestion!

    Posted by on 11 Nov 2016

    The cacao mint mixes easily, it tastes great, and is not sickly sweet like so many other brands I've used in the past.

    I'd recommend it to anybody!

    Posted by on 05 Nov 2016

    All the flavours we have tried are delicious. Vanilla is our favourite, it is delicious and isnt overly sweet like most powders we have tried.
    Delivery is super quick, never disappointed!!
