Thirty-three District Rose Societies in New Zealand are affiliated with the New Zealand Rose Society Inc. So, in effect, the National body is a "Head Office". The National body provides each member in New Zealand with:
District Societies also provide members with monthly meetings, a local newsletter, garden visits and occasional field days and/or seminars. Some District Societies also arrange discounts at various garden related shops and some purchase fertilizer and sell it to members at wholesale prices.
"Rose Ranfurly Shields" are competed for by a group of District Societies (from six to ten.) On these days the roses are pooled and are all entered in the name of a Society rather than by an individual.
Fees:
The cost of membership is set by each
District Society and varies from $25 NZ to $35 NZ per couple per year. Individual
membership is usually $2 NZ less.
Overseas members may join the New Zealand Rose Society Inc. for $40 NZ
