Waikato Regional Council ratepayers are paying $50 a night for deputy chairman Simon Friar to stay with family when he's in Hamilton for council business.
Mr Friar said the cost was "in line" with the council's allowances and reimbursements policy, even though he stayed at his son's house.
In an email answering Herald inquiries, Mr Friar said he had separated from his wife and she lived in the house they co-owned in Hamilton North, while his permanent residence was in Whangamata. He did not stay with her when he was in Hamilton.
He also co-owns a property in Fairfield with her.
Mr Friar came under criticism from his peers this week after his expenses for the year to the end of June totalled $40,000, a quarter of which was for food and accommodation.
