Murray Chisholm (021) 1389907

Chairman of IYNT NZ:

Murray Chisholm is Assistant Head of Science at Wellington High School. He has been involved in NZYPT since 2008 as WHS team leader and as a juror. Wellington High School have participated in the National Finals of NZYPT frequently in the last 8 years and were the 2018 National Champions.

Murray took a team to the first Junior Young Physcists' Tournament (JYPT) in Sydney in 2010. The JYPT was organised to give students under the age of 16 experience in a physics tournament. This was so that they would be better prepared for the tournaments used to select the IYPT teams of Australia, New Zealand, Singapore and South Korea. Murray was the JYPT President in 2011 and director of the tournament held that year. He took teams from WHS to the first 7 editions of the JYPT, finishing runner up 3 times and in 3rd place twice.

Looking for a way to expand the tournament concept beyond physics, Murray took a team to the 5th International Young Naturalists' Tournament in Nanjing in 2017. The whole team representing NZ were from Wellington High School, and they won. In 2018 a second team from Wellington High School traveled to Tbilisi for the sixth IYNT and placed 3rd.

Murray was tournament director of the first NZYST held in 2019 at Wellington High School. He then organised the selection and preparation of the New Zealand team for the 2019 IYNT in Minsk. The NZ team won the tournament.
