A new poll shows more New Zealanders think the country should stay a constitutional monarchy than those who would like it to become a republic.
The poll of 500 people by Research New Zealand asked whether New Zealand should consider becoming a republic.
Forty-eight percent of those surveyed supported the Queen's position as head of state, while 42% were in favour of a republic. The rest were undecided.
Research New Zealand's director Emanual Kalafatelis says although the results showed a greater number of people wanting to retain the Queen as head of state, the critical result was the increase in those wanting a formal consideration of the country becoming a republic.
Research NZ says in previous polls, the number of people supporting the idea of a republic was about 25% to 30%.
According to the latest poll, women and those aged over 40 were more likely to support the monarchy, while men and younger respondents were more likely to favour a republic.
The research showed 45% of respondents support Britain's Prince Charles becoming the next king, while 43% preferred his son Prince William.
Women and younger respondents were more likely to support William as head of state.
The poll has a margin of error of plus or minus 4.6%.
