About Us


Greg Jamieson Greg Jamieson
Greg has had a passion for horses all of his life. He began working with horses and starting them under saddle for clients while still at school and specialised in showjumping at a young age. His first major achievement was at the age of 18 when he rode his own home produced 6 year old horse "Chichester" to win the prestigious Bell Tea Grand Prix at the Horse Of The Year show. Following this he won a string of Young Rider classes and Grand Prix all around the country. At the age of 22 he won the NZ World Cup Showjumping Series against many more seasoned combinations. He then went on to represent New Zealand in Australia where he qualified for the World Cup final in Gothenberg, Sweden. During this busy competitive time Greg worked fulltime on the family dairy farm while continuing to break in and school horses for clients all over the Waikato, BOP and Auckland areas.

Greg spent 5 years at the world reknown "Cambridge Stud" working as stallion manager, assistant yearling manager and private breaker and pre-trainer of the studs very valuable Thoroughbred youngstock. He also spent 2 years at Westbury Stud in a similar role. This gave Greg further knowledge and experience that enabled him to establish his next very successful business "Chester Stables" in Pukekohe, breaking in and producing young horses to competition level while continuing to coach riders of all levels. In recent years he has produced, amongst others, the 2 outstanding "Ramirez" geldings "Hez Zurich" and "Retrospect II", and the Holsteiner stallion "Vollrath Chagall", all successfull to Grand Prix level.
Now based back at his family property "Chester Farm" in Paeroa where, alongside privately producing the next generations of the young Chester Farm Warmblood horses for competition and sale, Greg is available to assist local riders and horse owners by taking on a limited number of horses for training as well as being a highly regarded and popular coach known for his very professional, systematic, effective and enjoyable riding lessons for horses and riders of all levels and disciplines.
In January 2017 Greg made the decision to retire from regular competition riding meaning he is now able to concentrate his time on coaching and producing riders and also extending his exciting Contact Care therapy.


Diana JamiesonDiana Jamieson (nee Fowler)
Diana has grown up with and ridden horses from a very young age, competing in dressage, showjumping and eventing for fun until the age of 17 when she started work in graphics and design, later running her own website design business.
When she moved to Christchurch in 2002 looking for a change in direction, Diana and her mother Sue Fowler (a lifelong horsewoman to whom Diana credits much of her practical horsemanship and knowledge) established the now very well known "Astek Stud" where they set about breeding and producing top quality warmblood horses for all disciplines - from conception to competition this greatly enhanced Diana's knowledge and experience in all facets of horse stud management including breeding, handling, breaking in and riding young horses through to stallions.
Having spent time with the likes of highly regarded international horseman Buck Brannaman and Ken Faulkner, Diana's main passion lies in handling young horses and "problem" horses, gaining their trust, confidence and respect in-hand before progressing this soft feel, communication and balance into work under saddle - playing an important role in the day to day training of all horses in work at Chester Farm.

Diana also brings to Chester Farm her quality youngstock from Astek. Two of her oldest home-bred and produced horses "Astek Gianni" and "Astek Gymbya" have been very successful with Diana in their light competitive careers to date, with Gianni being crowned "NZ National 5yo Showhunter Champion 2010" in her first season competing under saddle, followed by "Reserve Champion Amateur Showhunter Of The Year" at HOY, while younger sister Gymbya is already following in Gianni's footsteps, winning "Waitemata Summer Series Showhunter Champion 2014" in her first season of competition.
Since arriving in the North Island in 2008, Diana has thoroughly enjoyed returning to occasional competition and quickly established a reputation as a popular and competitive rider recognised for her well produced horses and professional riding style.
Her naturally calm postitive nature and practical, actionable advice has seen her become an increasingly sought after coach due to her encouraging approach and strong foundation methods, including developing two very unique training camps aimed at both young riders and adult riders.
