Blackie lived on Maungakawa Hill for 15 years with his wife Pam and planted many Rewarewa which attract tui. He planted hundreds of daffodil bulbs there to identify the outline of the historic TB sanitorium that used to be there. With Pam he was engaged in researching the history of Sanitorium Hill from Maori times to the present day and this material is now held by the family waiting to be written up.
