in ongoing costs. They compared this cost to the president of Ireland, a head of state of a country with a similar population size, who cost €3.4 million – NZ$6 million on the exchange rate at the time. Monarchy New Zealand accused the republic supporters of arbitrarily inflating the costs on the governor-general, pointing out the Irish President's cost was closer to NZ$12.8 million once the extra costs were included. Public opinion , the New Zealand public were generally in favour of the retention of the monarchy, with polls showing it to have between 50 and 70 per cent support. Polls indicate that many New Zealanders see the monarchy as being of little day-to-day relevance; a One News/Colmar Brunton poll in 2002 found that 58 per cent of the population believed the monarchy has little or no relevance to their lives.

An October 2011 survey of 500 business professionals asked "What Is Your Level Of Support For New Zealand Becoming A Republic?". 27 per cent said not at all, 24 per cent said somewhat opposed, 23.1 per cent were neutral, 14.8 per cent said moderately in favour and 11.1 per cent said
