I’M ALL ABOUT YOU, BUT HERE’S…

a wee bit about me.

As a wife and mum to two young girls, and someone who's navigated my own health challenges, I know first-hand just how hard and confusing it can be to find the right advice and someone who truly gets what you're going through. I've been there, and it's a big part of why I do what I do.

Based right here in Christchurch, I bring a strong scientific background, solid education and plenty of real-life experience to everything I do. Alongside the science, I've always had a genuine passion for food and for making healthy eating enjoyable, practical and achievable. When I'm not spending time with my family, you'll find me out running with our dog, at the gym, or in the kitchen creating wholesome, delicious meals that prove healthy eating never has to be boring.

Here's what I truly believe: we're all on our own unique health journey, and what works for one person won't always work for another. There's no one-size-fits-all here. My personalised, holistic approach is all about supporting long-term, sustainable changes, building your nutrition knowledge so you feel confident and in control, and improving your overall health and wellbeing for good.

This is about real change that actually lasts, and I'd love to walk alongside you every step of the way.

Nice things people have said

  • Go see Kathryn and she will find a way to get you on a path to a healthier you. Little steps, but the steps are the important thing and Kathryn is always there ready with the next idea to try, and the encouragement to help you feel like keeping on trying.

    I started as the epitome of unhealthiness, and after 3 months, have been making changes, not always consistent changes, but enough changes to get me going down in size and up in feeling better and getting through to the end of the day with some energy left to burn!

    You have nothing to lose and everything to gain, seriously. You will not regret getting in touch with her. Signed, an over 50 year old that used to drink too much, move too little and just eat whatever I wanted. :-)

  • After hitting menopause in my late fifties I was struggling with my weight for the first time in my life. My diet was healthy and I focused on eating all the right foods with little progress in losing weight. I had almost come to accept that this is what middle age looks like and there was nothing I could do about my weight gain.


    Meeting Kathryn gave me hope, she talked my language with food and outlined a new way of planning meals. It has been simple and after just two months my weight loss has been unbelievable.


    A huge thank you Kathryn, you are an asset to my professional support team.

    — Annette

  • KS Wellness has enabled me to finally find the balance that ensures I'm following the pathways that prioritise my goals and my health. Kathryn is so encouraging, determined to identify barriers and to find sustainable health solutions that work.

    I'm so very appreciative for the support and incredible knowledge Kathryn brings to a wellness relationship.

  • Working with Kathryn was just what I needed. She is kind, optimistic and very knowledgeable.

    I learned a lot, changed habits that wouldn’t previously budge and feel excited about managing my health for the future.

    Highly recommend to anyone who is looking for accountability from a trustworthy and empathetic Nutritionist.

    — Lauren

  • I highly recommend Kathryn and her services to everyone. She is very thorough in her analysis and was able to get to the root of my gut issues really quickly. She is a very clear communicator and worked with me as she provided a detailed nutrition plan for me to follow which has since transformed my gut health and my wellbeing considerably.

    I feel so much better, have more energy and hardly ever experience the gut issues I did before.

    Thank you Kathryn you are a life saver :)

    —Vanessa

  • I have had a few medical issues and struggled to work out the right path way to get healthy. Kathryn is amazing at what she does. I have seen great results.

    When My GP was letting me down, Kathryn made an excellent referral to a specialist who ended up getting me the help I needed.

    Would highly recommend her services.
