Inland lakes such as Aviemore, Benmore, Ruataniwha, Ohau, Pukaki, and Tekapo are open to fishing year round. For the remainder of May, Lake Camp will be open to fishing, closing on May 31. Remember that duck hunters will be on rivers, lakes, and ponds this weekend, and maybe anytime throughout the next few weeks. That's one reason why winter fishing on down-country rivers is halted until June 1. Make use of it.
Fish are in good condition and taking spinning tackle or feathered lure.
The best results will almost certainly come from fishing near inlet streams, taking special care to avoid fishing upstream on inlet streams. They are closed to fishing now.
