Welcome to Body Audit NZ

Body Audit NZ was founded by Michelle Rosewarne and business partner Kim Brown in March 2015.  Michelle and Kim, who both have business and management backgrounds, they were both looking for something new when they met at a Boxing class in 2012.  Kim realised her health and fitness were in need of a serious change and was lucky enough to do a similar test which changed her life, and that's when they quickly realised they needed to share this with others and Body Audit NZ was formed.



The BIA (Bioelectrical Impedance Analysis) test works by sending an extremely weak (and harmless) electrical current through your body. Your body's total weight consists of various "masses", like fat, muscles, bones, and water. Each of these conducts electricity in different ways. The more muscle a person has, the more water their body can hold. The greater the amount of water in a person's body, the easier it is for the current to pass through it. The more fat, the more resistance to the current.  By measuring the electric resistance of some of these masses in your body, called "Bioelectrical Impedance", the test is able to accurately measure what percentage of your total body weight is made up from each.


YOUR STATS EXPLAINED - Results are a guideline only and not to be taken as medical advice. The reason why we use height, age and gender data into the machine is to provide a reference range or a healthy guide to work within.  The reference ranges are provided in brackets underneath each itemised value.   You will notice that next to each value, the terms "optimal", "under" or "over" appear to provide a general guide that identifies how your individual results fit within each measured reference range.
