Ms Henry said while she knew the increase would come as a shock to some, she was okay with it because they were being categorised in the new rural residential category, which bought her rates bill to a similar level to the rest of the city.
"When we got the letter we actually laughed because we thought it was so funny ... we have had the luxury of paying a small amount of rates so I don't mind because it has been good for us."
In the east ward Rob Pascoe will see his rates rise by 11.3 per cent in the first year, Mark Bunting's are up 11.2 per cent, Paula Southgate's up 3.9 per cent and James Casson's up 2.7 per cent.
West ward councillor Leo Tooman is facing a 13.4 per cent increase, while Angela O'Leary's rates bill rises by $11 to just 0.45 per cent.
Deputy mayor Martin Gallagher will have the biggest reduction in rates of his fellow councillors for the two properties he has interests in, with a 5.3 per cent drop, shaving $286.05 off his rates bill.
Gallagher said it was "swings and roundabouts" for him as one of the properties he owned was dropping 17 per cent, but the other was facing a 47.5 per cent increase.
Councillor Garry Mallett's rates bill for his Chartwell property will also drop 3.9 per cent.
Only nine of the 12 councillors live in the city boundaries, with west ward councillors Geoff Taylor and Dave Macpherson and newly elected east ward councillor Ryan Hamilton all living on the outskirts. However, Mr Taylor confirmed he and his wife were selling their Rukuhia house and moving back to Hamilton's west ward.
Mr King did not return requests for comment from the Herald on Monday, but Hamilton City Council chief executive Richard Briggs said he expected to have another conversation with the mayor on Tuesday about whether he perceived there was a conflict and would seek advice from the Office of the Auditor-General, given the large number of properties he owned.
Mr Gallagher asked Mr Briggs on Monday to get advice from the city solicitor or Auditor-General about appropriateness of each
councillor voting on the rating proposal after learning about how many properties the mayor owned in the city.
"I've personally requested the chief executive run the rule across everyone.
"Without personalising it to anyone I would expect to receive advice about is there any elected member who should exclude themselves."
Briggs confirmed the city solicitor would be reminding councillors of their obligations around conflicts and their responsibilities within the next few weeks.
When Hamilton News contacted Mayor King on Thursday, he said the chief executive was away for the week and no conversation had been held yet. He was asked if he had a conflict of interest.
"I'm not entirely familiar with the situation, but the chief executive is away this week," he said.
Further comment was sought from Mr Briggs. Hamilton News was advised by the council communications unit that he was still away so could not provide an update. - Additional reporting Tom Rowland
