"It's not just a news item to us, he's our family member."
The woman said she was under the impression they would be the first to know if and when charges were laid.
She said she had since spoken to a man at the Ministry who had attempted to phone Mr McCulloch's sister and sent a letter.
"It turned out he had the wrong number for her and the letter only turned up this evening [Friday]. It's no good sending a letter and hoping for the best."
The woman said Mr McCulloch's sister had still not received a phone call from the Ministry despite her giving them the right contact number.
"I've spoken to the family about it and we just want to say 'hey we did not know about this, we should have been the first to know'. We're all in agreement that if we speak up it might stop another poor family having to read about something like this in the paper.
"To me and my family they could have tried a little bit harder. They could have asked the police for our numbers."
"It would be nice if our feelings and thoughts had been taken into consideration."
A spokesperson for the Ministry said it would "normally" alert families about prosecutions. He was unable to investigate further before Hawke's Bay Today went to print.
