The wedding of royal first cousins in Tonga this week has caused comment in New Zealand, with some Tongan New Zealanders opposing the union.
Crown Prince Tupouto'a 'Ulukalala is to be married to Sinaitakala Fakafanua on Thursday.
Community leader Will Ilolahia of Auckland says he is worried about the dangers of such close relatives marrying.
Mr Ilolahia says he agrees with the view expressed by Princess Frederica Tuita, who has called for the two to marry outside the family.
But he also says the wedding will be good for the Tongan economy and public morale during tough political times.
But lawyer, Kahu Baron-Afeaki of Auckland says it is traditional in Tonga for nobility to marry each other in order to keep the royal bloodline strong.
