What sort of sovereign will King Charles III be?

On February 6 1952 a young Princess Elizabeth was in Kenya when word reached her of the death of her father, King Charles VI. In that instant she became Queen, although her coronation came the following year. So today marks the first time since 1951 that Waitangi Day dawns without Queen Elizabeth II as our head of state. Now her son, King Charles III, is sovereign for the first time on our national day. What can we expect from him in the years ahead, especially as countries like Barbados abandon the monarchy to become a republic?
