Our NZ Whey Protein Isolate is produced in New Zealand from grass fed dairy cows that graze year round on New Zealand's green pastures. It is undenatured and made from cheese whey to deliver a concentrated source of protein.
NZ WPI is made from cheese whey and is processed through cross flow micro-filtration and ultra-filtration to enable the protein to remain undenatured. The result is a clean whey that contains over 93% protein (dry basis, natural flavour) with only 1% fat and 1.2% carbohydrates.
The flavoured options are made with organic flavours and natural sweetener, providing a convenient way to add protein to your diet.
The facts are:
- Cross Flow Micro-Filtration naturally isolates undenatured protein due to its low temperature process
- Undenatured Protein containing naturally occurring whey microfractions such as 43.8% Beta-Lactoglobulin, 20.3% Glycomacropeptide, 15.2% Alpha-lactalbumin, 3.4% Immunoglobulin, 1.2% Bovine Serum Albumen and small amounts of Lactoferrin and other minor proteins
- From Pasture Fed Cows raised on natural grass and clover pastures
- Free from Antibiotics & Genetically Engineered Recombinant Bovine Growth Hormone (rBGH)
- Free from acid processing
- Naturally Rich in BCAA's (Branched Chain Amino Acids)
- Very High Protein at 93.1g per 100g on a dry matter basis (Natural Flavour)

Best protein powder out there!
By: Josh on 24 September 2026Absolutely love this protein powder. I will not go back to the conventional protein powder that costs over $100 per kg! This powder is as clean as it gets, naturally sweetened, tastes amazing and the texture is great too.

Best Protein Powder!
By: Rachael on 24 September 2026The NZ WPI is by far the best protein powder I have consumed (and I have tried most on the market!) We haven't tried all flavours but are partial to the Organic Vanilla and Salted Caramel. Thank you for such a clean protein Professional Whey!

Great protein powder
By: Lauren Enfield on 22 September 2026We have enjoyed using this whey protein. It’s very pleasant. I’ve mixed it into smoothies, yoghurt and porridge. Very easily taken in a shake with milk also. About to order some more.

Legendary Product
By: Dan on 21 September 2026Absolutely amazing. Perfect natural taste ( I absolutely LOVE the unflavoured protein) WPI or WPC, I love both. Personal absolute favourite is the AUS Whey Protein Concentrate as it has nothing in it but WHEY !! Just be aware that it it s friction harder to mix as it has no "agent" in it. Just 100% pure whey and nothing else, I love it ! The NZ Whey Protein Isolate is also perfect. It has just whey and sunflower Lecithin in it and mixes PERFECTLY. Absolutely amazing pure products, way better and purer as a lot of established US brands. Thanks, Dan

NZ Whey Protein Isolate [Organic Cacao 1kg]
By: Ivan Ratchev on 21 August 2026Tastes awesome and super easy on the stomach. The Organic Cacao flavour is smooth, chocolatey, and mixes really well, the lactose is really low — great if you’re a bit sensitive to dairy but still want a solid protein hit. Just a clean, tasty, easy‑to‑digest option.

Organic cacao protein powder
By: AD on 10 June 2026This supplement is a great flavour to drink and very easy to digest first time using this product as I was told about this protein powder by my older brother and the only down fall to this is there is no PayPal or after pay would be very handy to purchase on a regular basis

Love this
By: Beck J on 26 May 2026I wanted a clean protein shake (no nasties) for the convenience for brekki and help with weight loss. I contacted support via email and they responded quickly and recommended the Whey protein Isolate. I than went to the site and ordered the vanilla and Choc flavors. The vanilla is nice with no yuck after taste. With the vanilla I add either frozen blue berries or frozen banana. The Choc is yum as well with no yuck after taste and I generally add frozen banana. Delivery was very quick like 3 days. Very happy with the taste, customer service and delivery time. Also a nice energy through out the day. Thank you Professional Whey team

The best protein powder on the market
By: Clair Cameron on 12 May 2026This is hands down my favourite protein powder. The ingredients are incredibly high quality, clean and simple, with no unnecessary fillers or artificial junk. It mixes well, tastes genuinely delicious, and feels light and easy to drink every day. You can really tell the quality is better than other protein powders out there. It's also the only protein powder that doesn't upset my husband's or my stomachs.

Purest and best WPI available
By: Rodney on 27 February 2026NZ WPI natural is the purest whey available. It has no artificial anything.... just the purest whey from New Zealand grass fed cows... It mixes extremely well in plain warm water, and can be added to yoghurt without altering taste... I have not found anything better than this.... the price is reasonable, and quality very consistent.. hopefully this review does not knock the price up.... its the best
(5)
Great quality protein powder
By: Alana on 18 February 2026Professional Whey is a fantastic quality protein powder without additives. It blends well and has a smooth texture. I love the unflavoured powder for versatility but I did recently try the chocolate mint flavour to use on the go and it was great.
(5)
5 stars!
By: Sarah on 5 February 2026I love how transparent the brand is around providing a clean protein. I’ve always struggled with the synthetic taste of proteins and the Professional whey flavourless NZ WPI is a staple for me now daily!

NZ Whey Protein Isolate (natural 1kg)
By: Liz on 4 February 2026Great product! Love that's it's natural and lactose free! I've tried other protein powders over the years but always come back to this one.
(5)
Smoothest protein ever
By: Ashley on 31 December 2025Recommended to me during pregnancy to meet my protein needs and I was so happy with it. Mixes so well with any liquid - not gritty, sticky or thick - super smooth and allows the other flavours you put with it to shine vs taking over. I also like it doesn’t make me feel sickly full, it’s satisfying yet light! Excellent product can highly recommend.
(5)
NZ Whey Protein Isolate [Organic Cacao Mint 1kg]
By: Gilbo on 18 December 2025Best in the business. Have switched from ON Gold Standard to R1 without success but then I went and ordered this - absolutely blown away Gives me zero gut problems, tastes amazing, is the right price and i'm certain it's helping my goals more too. Zero complaints. Maximum love.
(5)
Wouldn’t by any other protein powder
By: Rene on 6 December 2025I absolutely love this protein powder, I’m sensitive to dairy so being able to have protein powder that doesn’t upset my tummy is fantastic. Not only is it gentle it’s super high in protein and the formula turns out beautifully, I use it in a blender to make a smoothie and the consistency is just heavenly. Knowing there are no nasty additives either gives me peace of mind. It may be a bit more expensive but I’d rather pay for a quality product then fill up on a powder full of junk.
(5)
Yummmmm!
By: Kelly on 4 December 2025Professional Whey have THE best WPI.
(5)
Versatile deliciousness
By: Adelle Kaps on 29 November 2025This protein has been a huge hit for our family. Daily smoothies, in our protein bliss balls and mixed in to our overnight oats. It’s delicious and mixes so well. So easy to get the extra protein in to our very active children! Highly recommend.
(5)
WPI review
By: Sophie on 7 November 2025Absolutely love the WPI from professional whey. I like to make sure my diet doesn’t consist of any nasties or additives and is of high quality with natural high quality ingredients. It’s so comforting to find a company that also cares about producing these foods/powders and being able to sell them at an affordable price!
(5)
Best WPI by a long way
By: David on 6 November 2025This is the best and cleanest WPI on the market.Please do not stop making it in this flavour.
(5)
Great Natural Product
By: Karen C on 31 October 2025We always buy WPI from NZ because it's from New Zealand with a "no frills packaging" (better for the environment). It's exceptional in fact, as it blends really well into whatever type of protein smoothie we like or just plain with milk or a vegie type milk (if lactose intolerant) and add a little goji berries or freshe/frozen berries for some natural flavour. Our whole family uses it and it's reasonably priced compared to other fancy packaged brands, where you're paying for the packaging that has to go to landfill... Fantastic product all round!
(5)
Great products, have been buying for years
By: Lynn B on 27 October 2025Will never stop buying, best taste, quality and excellent service. Keep it up. I often mix the WPI into coconut yoghurt. Yummy!
(5)
Yum!!!
By: Rachael on 24 October 2025I honestly LOVE this protein - it’s so delicious. Even though it’s vanilla it kind of tastes like cookies and cream. Great as a shake and I love adding it to my Greek yoghurt makes it so tasty. I think it’s good value for money since we are getting clean quality protein.
(5)
Delicous
By: Raana on 24 October 2025Probably the first protein powder that tastes delicious, also keeps me full for hours. Loving it. Have recommended to many.
(5)
Delicious!
By: Maria R on 20 October 2025Goes down well, no funny after taste, I have even started my fussy mum on it, great quality product, will continue buying! between my husband and I we have gone through about 8 bags! you wont regret it! Dont fall for the over priced overseas products, they are either terrible quality or BS about the results. Support an aussie business (I dont get paid BTW just another small business owner who understands the struggles)

Healthy and Reliable Whey Powder
By: Mabel Cheng on 15 October 2025My first order turned out to be a pleasant experience as I initially ordered Hydrolysed powder but changed my mind. The customer representative patiently answered all my queries and provided me with a lot of additional information on other products which I will try next time. They were prompt in amending my order and processed the refund.
