Phil Davison

Born in 1959, Phil Davison began training in Judo as a child, but dropped out of martial arts practice during his teenage years. In the early 1980s he began the study of Hapkido under Master Sung Do Kim at the International College of Hapkido on Paramatta Road Strathfield, Sydney. During the first year he trained full time under Master Kim, Duncan Schofield and Trevor Rant. Phil also trained under Hapkido Master Cha Won Gyu, in addition to study of Jujutsu and other related arts. In 1987 or 1988 he began training in Muso Jikiden Eishin Ryu under the tutelage of Anthony Karasulas Sensei. During 1991 Phil traveled to Korea to further his study of Hapkido and to Taiwan where he lived, teaching English and studying White Crane Kung Fu with Master Chen Wu Chang in the town of Lukang in Chungwha County.

Returning to New Zealand, he founded the Seishinkan club at Auckland University in 1993. In 2000 he moved to Dunedin and established the Dunedin Seishinkan dojo. He has also made several visits to Japan to further his study of martial arts, participating in Daito Ryu Jujutsu and sword training. In 2004 he was appointed New Zealand Shibucho (branch head) of Komei Jyuku Muso Jikiden Eishin Ryu by Sekiguchi Komei Sensei. He is a former CEO of Jujitsu New Zealand and was one of the first committee members of the Jujitsu Federation of New Zealand. He continues to travel to Japan as often as possible for further training with Sekiguchi Sensei. In 2014 he was graded to 5th dan in Aiki-jujutsu by a panel consisting of Peter Grenetsky and Duncan Schofield.

Phil holds an MA degree from Waikato University and a Bachelor of Music degree from Auckland University. He is also a photographer and filmmaker, best known for the low budget horrors "Ghost TV" and "Kung Fu Vampire Killers" and often works as a teacher of filmmaking. He lives in Dunedin with his partner, Pamela, and young daughters, Sophie and Willa. You can find more information on Phil's activities as a film and photography on and

Nicholas Coldrick

Nicholas started his martial arts training in 1992 in Combined Martial Arts, but quickly decided the style was not for him. Six months later, he discovered Seishinkan at the University of Auckland dojo. In 2000, after being graded to 2nd dan by Duncan Schofield, he took over the Auckland dojo when Phil Davison moved to Dunedin, and has been Dojocho (dojo head) ever since.

In 2002 Nicholas travelled to Sydney to train with Sekiguchi Komei Sensei and Master Bruce Watts, and in 2004 he travelled to Japan to further his training with Sekiguchi Komei Sensei. He has since travelled to Japan again to further his training in Komei Jyuku with and trains with Sekiguchi Komei Sensei at least once a year. In 2012 he was appointed Auckland Shibucho (branch head) of Komei Jyuku Muso Jikiden Eishin Ryu by Sekiguchi Komei Sensei. In 2014 he was graded to 4th dan in Aiki-jujutsu by a panel consisting of Peter Grenetsky and Duncan Schofield.

Nicholas has a MA degree in English Literature from Auckland University and is a full-time and contracting technical writer. He lives in Auckland with his wife, Vanessa.

Shanon Coxall-Jones

Shanon began his studies in the martial arts as a teenager in a Tae Kwon Do variant. He left in 1996 after deciding that the style didn't suit, and didn't return to martial arts until 1999, when he enrolled at the University of Auckland and started his training in Seishinkan Bujutsu.

He was graded to first degree back belt by Master Bruce Watts in November of 2002, and later to second degree by Sensei Phil Davidson and Sensei Nicholas Coldrick in December 2004.

Gary Wilkins

Gary's first contact with martial arts was while he was still in secondary school back in his home town of Sydney (yes, that does technically make him an Australian, but he is mostly over that now). He trained for a year in Kumdo (the Korean variant of Kendo) under Masters Song and Kim at their dojo in Strathfield.

It was over a decade later, after moving to New Zealand, that he rediscovered sword work at Seishinkan Bujutsu under the tutelage of Sensei Phil Davison. In November of 2003 Gary was graded to 1st Dan and in May 2005 travelled to Japan to study under Sekiguchi Komei Sensei. He was graded to 2nd Dan in November 2005.

Gary has a Masters degree in Electrical Engineering from Sydney University and is a full-time software engineer. He lives in Dunedin with his partner Marie (a genuine Kiwi).

Giles Coverdale

Born in 1981, Giles has been training in Seishinkan since 2000, and was graded to shodan in 2004 by a grading panel lead by Master Bruce Watts and Phil Davison with other Seishinkan and Wind School instructors. Giles was graded to nidan in 2006 by Sensei Phil Davidson and Sensei Nicholas Coldrick. He studied law at Otago University, graduated in May 2004 and passed his bar exams at the end of that year. He is currently working full time in Auckland doing property law. In his spare time he enjoys socialising and the outdoors.

Glen Webster

(Glen Webster passed away on June 20th 2007, and we are still saddened by his loss. His biographical note is left here as a memorial.)

Glen Webster has been training in various martial arts for over 30 years. Judo was his first style and he has attained the rank of shodan and recognises that often Judo is his first response to an unfamiliar situation. He also studied shotokan karate about 20 years ago and attained the rank of brown belt in that before transferring his training to Tae Kwon Do and obtaining a first dan in that. He moved onto Hapkido where he attained a first dan in this style that allowed him to combine his grappling experience with joint locking and striking skills. Since then, Glen was fortunate to have trained in a number of Jujutsu dojos in Perth, Cape Town and Auckland before returning to invercargill. He set up an Invercargill dojo and has found that Seishinkan offers him the opportunity to combine his varied experiences and to continue to develop his expertise under the complementary approach that the Seishinkan system offers.

Daniel Hofmann

Daniel started training Shotokan Karate in Germany for 2 years. After moving into a different town and having trouble finding a new and suitable dojo his martial arts training dwindled and came to a standstill in mid 1999.

In January 2005 he decided to restart martial arts training under Sensei Phil Davison in Dunedin. He was graded to shodan in Jujutsu and Bojutsu by Sensei Phil Davison and Sensei Nicholas Coldrick in November 2006.

Daniel now lives in Wellington with his partner Andrea and is writing his PhD in Social Anthropology.

Peter O’Neill

Peter O’Neill is one of six brothers all of which had belonged to the Invercargill Judo Club. Peter took up judo after one of his younger siblings (who knew some judo) ‘put him on his backside’. Peter started training the following week under the instruction of Dave MacDonald (4th Dan). After placings at South Island and National Judo Competitions Peter travelled to Japan with the New Zealand Team. He had a short stay at the Nipon Budo Budokan and competed in the Shiriki Cup International Judo competition .

On return to New Zealand Peter and his wife decided to start a family and so judo took a back seat for a while, however financial pressures encouraged him to get a second job as a bouncer, putting his judo skills into practice. This job lasted for 10 years.

Peter along with Glen Webster reformed a new judo club after the old club closed down. After having trained for twenty something years each as a judo players Peter and Glen decide to change their focus to a traditional style of martial arts. Having looked at many clubs and styles Seishinkan JuJitsu was found to be the system which suited them best.

Peter has the grade of Shodan in Goshin Jutsu, 18 November 2007.
