National Office Staff

Chris Duggan - National Founder & CEO

Chris trained as a Biochemist at Massey University and taught secondary school science, biology and chemistry for 15 years in the Bay of Plenty. Throughout her teaching career Chris had a growing sense of concern about the lack of science knowledge students had when arriving at high school. When she read an E.R.O. report in 2013 that stated over 70% of NZ's primary and intermediate schools lack an effective science programme, she decided something needed to be done. She left her middle management and teaching role mid 2013 and the rest - as they say - is history.

Chris now leads a small but effective team that develop new science resource kits, assemble kits to send all over the country, train new staff and support the growing number of regions establishing their own House of Science trusts.

Dr Siouxsie Wiles

House of Science Ambassador

“The House of Science model is brilliant – the science kits are amazing and make science accessible for all primary schools. Science is a resource-hungry subject so by sharing these kits among a group of schools it allows access to quality resources covering the whole science curriculum. I feel very honoured to be given this role as Ambassador for the House of Science. I hope that I will be able to help the charity raise awareness of their amazing and important work."
