By the time staff reached Hewgill's room he had reportedly already been knocked unconscious. He died in hospital a couple of days later.
The man who allegedly hit Hewgill had been a well known boxer in the town he lived.
"I don't want any charges laid against this man at all," Hopkins said.
"It's most unfortunate because these people have no idea what they're doing. The other family are absolutely devastated. I feel so bad for them."
Hopkins described her father as a "railway legend" who was one of the last Taumarunui train drivers, and was looking forward to his 100th birthday this year.
"He asked me once, 'Do you think they will give me a party?' "Of course', I said."
Police said enquiries into the circumstances of Hewgill's death continue.
