Thank you!

Our 2023 Expo saw 273 science experiment, research, technology and art exhibits created by just over 600 students from 19 schools on display at Founder’s Heritage Park in Nelson on 22-23 August. These projects were assessed by 56 volunteer judges.

Welcome to the Cawthron Scitec Expo.

This event encourages and supports Nelson Tasman students to explore science through topics of personal interest.

Independent judges, including Cawthron scientists, review entries, interview students and provide individual feedback to all entrants. Plus there’s a raft of prestigious awards and cash prizes up for grabs.

Our founder, Thomas Cawthron, believed science was the key to a better future. This event sees local schools, organisations and businesses collaborating to inspire the next generation of scientists in Te Tau Ihu.
