Susan Henricksen – Academic Manager

PGC(EdLM), GCHE, BHSc (Comp Med), Adv Dip Med Herb, Adv Dip Nat, Dip Hom

Education has always been a passion of Susan’s, especially to seek knowledge around medicine. Following a long career in a Medical Pathology Laboratory, Susan sought education in complementary medicine as a source of a more holistic approach to wellness. This resulted in Diplomas in Naturopathy, Western Medical Herbalism and Homeopathy and a Bachelor of Health Science. Practise gave way to education again and Susan started teaching at the Colleges she had trained at and also with Pharmacy staff as a Sales Rep with Naturopharm. Following six years at NZ College of Massage teaching Anatomy and Physiology, Pathophysiology, Research and managing the Auckland site, Susan has returned to her Homeopathy roots at CNHH after undertaking the role of Academic Manager. Susan draws on her knowledge and experience to support the students in their study in Homeopathy. There are also plans for a Masters in Education, the search for knowledge never ends!

Levonne Kelly – Tutor (Animal Homeopathy)

DipHom (Animal Health), RCHom, Cert Equine Practice

Levonne graduated from the Bay of Plenty College of Homeopathy in 2012 with a Diploma in Homeopathy (Animal Health).

She is also a full member of the New Zealand Council of Homeopaths, and commenced her role as Animal Homeopathy Tutor for CNHH in May 2017. Levonne’s background is very much animal orientated, with a Certificate in Equine Practice (Thoroughbred Stable Practice) gained during her years in the racing and breeding industry. She also spent several years working in a large Auckland veterinary practice (companion animal), as well as several in the veterinary pharmaceutical industry. At various times in her life she has enjoyed helping out on sheep and drystock farms. Levonne and her partner Don currently share between them three daughters, two horses, one dog, one cat and an assortment of beef cattle – a constantly evolving menagerie! Levonne is very active over the summer months with side saddle showing on her mare Tudor Rose, and during the rest of the year rides for pleasure as often as time allows.

College Support Staff

Reneigh McLean – Administration Manager

Reneigh brings a wealth of experience in campus administration, process improvement and customer service to her role as Administration Manager for CNHH. Previously at the NZ College of Massage as Reception/Administrator,  Reneigh managed a high volume, multiple programme campus administration whilst ensuring an exemplary customer service experience. With a bright, bubbly personality Reneighs brings a fun, light hearted approach to her role which is warmly welcomed by staff and students.

Anne Kohu – Student Engagement & Priority Learner Support


Anne’s inquisitive nature means she draws on experiences and inspiration from a broad spectrum of industries from the service industry to telecommunications installation work. However it was a health scare that sent Anne on a different journey of discovery. It was a coffee group in the early 1980s where they talked about homeopathy for the family and for cows at calving time that lead her to study with BOPCOH in 2001. Anne manages the Tauranga office of CNHH including maintaining the College learning management system (Moodle) and is our Maori Liaison Officer.

Deborah Joy – Student Engagement & Graduate Support


Becoming a parent opened Deborah to alternative, (organic, sustainable) living. Deborah has studied many healing modalities and worked in administration for over 20 years. A move to the Bay of Plenty coincided with the opportunity to join the team at CNHH so now Deborah has the trifecta of her beliefs, passions and experience in one.

Jennie found her interest in Homeopathy blooming alongside the passion for organics and completed both the ‘human’ and ‘animal’ Diploma programmes at the Bay of Plenty College of Homeopathy.
