He still does consultancy work, much of it involving birds and windfarms. His current areas of research are conservation management, industry attitudes to sustainability, and urban ecosystem management.
Dr Craig has been a leader, both nationally and internationally, in conservation, and is known for his role in the initiation of the Tiritiri Matangi Open Sanctuary. He has won international and New Zealand awards for his conservation achievements.
He believes New Zealanders don't value native biodiversity highly enough.
"We think it's free, but it costs money to manage it," Dr Craig said. "We need to realise that conservation - which is just part of sustainability - is going to cost money, but we can make money out of it (as he and Anne are doing with their TahiNZ.com farmstay business)."
New Zealanders needed to see biodiversity as part of their heritage and work toward increasing links with it.
