Try ringing one of the Working Men’s Clubs and ask if they have a fishing section. Also ask at the big tackle stores if they know of any surfcasting clubs around Dunedin. Often small fishing clubs don’t seek publicity and can be quite informal. I have found that many fishing clubs in the South Island have a go at many types of fishing. For example members of a trout fishing club may also organise club surfcasting competitions and book sea charter trips together. I once went surfcasting at Haast with members of the Upper Clutha Anglers Club!
