The alcohol-free, life jacket-compulsory race will start on the banks of Ohaaki Marae at Piripiri Rd at 11am and finish at Vaile Rd Reserve, where prizegiving and a barbecue will be held.
Funds raised will go towards the local club putting on a community Drought Shout, consisting of live music, food and refreshments, at the Reporoa Rugby Club on March 23.
"The Reporoa area is currently very dry, and many farmers have opted to start once-a-day milking, instead of twice, to combat low grass-growth rates ... and protect the condition of their herd."
Raft pre-registration is open at $5 per person, or $10 per person from 10am on the day. There will be spot prizes. For more information, or to register, contact Victoria Crafar on (022) 065 2125.
