"We can cover off numeracy, literacy, science, social studies among others using nature as the education source from year one onward. Art is another, obvious topic."
The programme's future plan is to involve six schools each year, in either student or teacher programmes.
Ms McCool is working with EIT Hawke's Bay on an education partnership which will see nature-time teaching principles integrated into the curriculum for year 2 and 3 candidate teachers.
In a 2014 education pilot, more than 150 students from Port Ahuriri, Haumoana and St Patricks Schools headed outdoors to learn about the role of trees, birds and insects in the local environment.
Cape to City's sister programme, Poutiri Ao ō Tāne, worked with classes from Flaxmere School, TKKM o te Wananga Whare Tapere o Takitimu and Hastings Intermediate last year using the same nature-time teaching principles.
Organisers hope the programme will be adopted by all schools within the Cape to City catchment area as well as schools in other regions and cities.
