Welcome to the Cawthron Scitec Expo.

This is an annual event that 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.

This year’s event.

Thanks to everyone who participated in and visited this year’s Cawthron Scitec Expo at Founders Park in Nelson on 6 September.

Nearly 60 projects were submitted by students from Nayland College, Nelson College, Nelson College for Girls, Rai Valley Area School, Waimea College and Home School.  Prizewinners are being notified and invited to a prizegiving presentation at Pūtangitangi Greenmeadows Centre in Stoke on Tuesday 27 September. 

The full expo for Years 1-13 will return in 2023.
