Here is all of what Hopkins has to say on the matter:
"XVII. Bee Forage: Bees in Relation to Horticulture and Agriculture
"The native bee forage of Australia and New Zealand differ entirely from each other. In the former country the various kinds of Eucalypti, and some of the Acacias, form the chief honey-bearing flora from which the greater part of the commercial honey marketed is gathered. Most of the forest trees indigenous to New Zealand, and there is a great variety, are honey-bearing—some of them remarkably so. It is a fact, however, that the bulk of the honey gathered from the native flora in both countries does not hit the public taste for table use, I have tasted, what I considered, some very fine honey in Australia, gathered from the Gums (Eucalypti) and it is undeniable that we have equally as fine bush honey in New Zealand, but the fact remains that the demand for it is small as compared with that gathered from white clover.
"For manufacturing purposes, nothing could be better, as the stronger flavour of the native honey would be more suitable for making up than the milder flavour of clover honey. At present, unfortunately, we have no extensive factories using honey, consequently there is little demand for it for business undertakings of this nature, and the cost of carriage to Europe for low grade honey is too great to pay the sender.
"WHITE CLOVER HONEY.
"There is no room for question that honey gathered from white clover blossoms is the best we know of, and is in the greatest demand the world over. There is no part of Australasia where white clover flourishes so luxuriantly as it does in most parts of New Zealand, and in some districts clover honey is obtained in its purest condition. The honey which fetches the highest prices on the European markets is from clover, with a proportion of what is termed “dandelion” honey in it, the latter gives it a more pronounced flavour, and a nearer approach to a bright amber colour, so much desired. In Chapter V. I have already advised the prospective commercial bee-keeper to choose a good clover district for establishing his business, and this as a rule, is associated with dairying."--Isaac Hopkins, 1911, The Australasian Bee Manual
