Ball appeared hard of hearing, asking the judge to repeat a statement at one point.
Defence lawyer Louise Elder said Ball had not had the opportunity to go through all the material received from the police in disclosure.
Ball faces five indecent act charges, two counts of indecent assault and one charge of sodomy against a boy aged 12-16.
He also faces charges of an indecent act and indecently assaulting another boy aged 12-16 and one indecent assault against a 7-year-old boy.
Detective Sergeant Bill van Woerkom of the Masterton police child protection team said people had come forward with more information since Ball was charged. "We've had a very positive response from the public."
Ball was remanded on bail to enter a plea on September 17.
