They are likely to undergo cross-examination before a judge makes a decision on whether Kelland is mentally fit.
Kelland was under the "shared guardianship" of Child Youth and Family when he allegedly attacked the tourist. He had been living on Waiheke with his foster mother.
Police allege he attacked the tourist on a walking track between Delamore Drive and Owhanake Bay, near Oneroa. She had been in the country only a matter of days.
Bloody and bruised, she managed to escape and sought help from builders working nearby. Police were alerted and arrested Kelland soon after.
Child Youth and Family have confirmed they had been involved with Kelland. Northern regional director Sharon Thom told the Herald in January that his agency had a "shared guardianship" role.
