Lynne has had a long time interest in Bonsai but did not join the Otago Bonsai club until 2008, this was after a workshop held by the club. In 2015 she took on the roll of club secretary.

Lynne enjoy working on all tree types and enjoy the challenge of working with our natives.

Tony Bywater
Tony Bywater

Tony joined Christchurch Bonsai Society around 1976 or ’77 and has taught the beginners class since the early 1990’s, served as President and Vice President of the society and chair of the organising committees for the 2009 and 2015 National Conventions. He regularly demonstrate at the Christchurch club and at local garden clubs and shows and is on the list of National demonstrators.

A university graduate in Agricultural Science, he’s largely self-taught in bonsai but has learned a lot from workshops with Ben Oki, Tony Bebb, John Hanby, Nobuyuki Kajiwara, Salvatore Liporace, Lee Wilson and Robert Steven.

Tony tends to favour deciduous trees., likes high branching trees, working with rocks, and a Chinese influence. He’s keen to develop his skills and knowledge with NZ natives. Whilst he’sm happy to do it, he thinks we spend too much time in our clubs working on starter material, usually from nursery stock; we don’t spend enough time developing our better trees. Really enjoys critique sessions, especially when people bring along trees they have been working on for a while.

Martin Walters
Martin Walters

First started bonsai in London in 2002 with a couple of shop bought trees on the roof of his house. On returning to NZ and owning a house with a garden things got more serious. Martin became a student of Bob Langholm 10 years ago and attend his workshops and had private tuition on a regular basis. He has attended workshops by Tony Bebb, Lee Wilson, Rob Kempenski and Nobuyuki Kajiwara.

Martin has attended BCI conferences in Australia and belong to the Auckland and Hamilton bonsai clubs.

He loves working on the refinement of older and collected materials, through wiring and carving and major branch shaping, collecting mugo and black pine trees and has a passion for large cedars. In his collection he has a number of large forrest plantings and chinese style penjing landscapes.

Martin would like to actively push bonsai in NZ in a more artistic direction with the use of our native trees and break some of the more traditional rules.
