Promoted with the idea of bringing together Railway Workshop employees who were interested in horticulture, the Otahuhu Railway Horticultural Club, was formed during the month of August, 1931. The founders of the club were Messrs. F. A. H. Blackford, R. Pointon and K. C. Brown—all at that time on the staff of the Otahuhu Railway Workshops.

Commencing with forty members, the club in a little over twelve months has grown to a membership exceeding 200.

At the annual meeting of the club, held at the end of the financial year, the rules were amended to include all railway employees, and also superannuated members. All branches of the Service are now represented, and at every meeting night more nominations are received. Any active or superannuated member of the Railway Service, also a member's wife and family (family meaning children under fourteen years of age) are eligible to join the club, the subscription for the year being 2/6 per member, including his wife and family.
