First, wait to see what the public thinks before expressing an opinion. Then come out in defence of reaction and reactionary institutions. Of course, this is no novelty for Labour 'leaders'. They are mostly imperialists to their toenails. Consciously - usually, or unconsciously, they know their role in the scheme of things capitalist and perform it, i.e., to serve the interests of the monopoly capitalists and to seek to adapt the interests of the working class to those of the monopolists.
Every negative has a positive and vice-versa.
The negative impact on the monarchy of recent events therefore has its positive side. In exposing the cold disinterest of the top royals, Diana's death has given a positive boost to republicanism in Australia, for instance. Australians have always had a more radical approach to the monarchy than New Zealanders, who like to think themselves more English than the English. Far and away the best sort of republic for the exploited masses would be a working people's republic such as the Workers' Party of New Zealand calls for in their Party Programme. But that, one must say, is not just around the corner.
