Margaret Holloway, Director of Business

Before establishing Nemidon Gels, Margaret initially trained as a registered nurse, specialising in coronary care and leading a ward. After several years of juggling the work as a nurse and raising four children, she moved to Wellington and began studying Science at Victoria University . This study led to her working with Crop Research, focusing on growing Lavender oil in New Zealand. This work nurtured her passion and interest in how to grow good crops to provide high quality essential oils.

This passion guided her to realising the best way to maximise her skills was in creating added value products. However, knowing that the cosmetic industry was saturated, she focused on health associated topical applications and teamed up with Dr Ian Miller, a world- leading expert in seaweed colloids to develop the concept which is now Nemidon.
