Sasha Temaru 

Founder and Head Trainer

With a sporting background and a passion for physical activity I was destined for a career in the fitness industry.  Over the last 4 years I have worked as a trainer in commercial gyms around Wellington. I have been lucky enough to work with a number of different groups and individuals, I have been a part of many journeys and have witnessed many incredible transformations.

In 2017 I created Grind Health and Fitness, a business that was inspired by the 3 things I love most in life;

  • Family;
  • Fitness, &
  • Fun.

I wanted to create an environment where people from all walks of life could come together and train in a fun and supportive environment. As much as that’s a big part of Grind I also live by the notion that ‘nothing great in life ever comes easy’. My training style will challenge you, I will encourage you to push past your boundaries and comfort zones, I will test you physically, mentally and emotionally but just know I will have your back, the team at Grind will have your back, now its time for you to back yourself, take the leap and I promise you won’t regret it.

Take a peek at me on Maori TV's "School of Training".


Toni-Faith (Fizz) Temaru

Boxing Trainer

Sport, health and fitness has been a massive part of my life from a very young age. Growing up I competed in a number of different sports, some of them at representative level. My passion for health and fitness led me to Otago University where I studied a Bachelor of Physical Education and a Bachelor of Arts majoring in Psychology. I have always been interested in the mental side of sport and fitness and I am a true believer that with a strong mindset you can achieve anything.

In 2015 I decided I wanted to challenge myself and try something new, I signed up for a charity boxing event and 14 weeks later I stepped into the ring for the first time. With a victory under my belt I wanted more and since then have gone on to compete in 2 further corporate fights. In June 2018 I took the next step in my boxing career and competed in my first amateur fight, of which I hope to have many more.

Boxing has taught me you can always be fitter, faster and stronger then you think you are so you have to find a reason to keep wanting to be a better version of yourself. I am excited to share the skills and knowledge I have learnt through boxing and sport in general, to provide you with challenging but fun workouts. The Grind whanau have your back and will encourage and support you every step of the way.
