Watch live as Tom Walsh, Valerie Adams and Eliza McCartney all participate at the Graeme Douglas International Track Challenge in Auckland.
Walsh, the current world outdoor and indoor champion will compete against a top class international field of competitors from USA, Canada, Jamaica, Poland and Australia, including the two other medallists from the Glasgow 2014 Commonwealth Games, O'Dayne Richards and Tim Nedow.
Walsh has had two big wins from the first two shot put competitions of the series in Timaru and Christchurch last week and will be very keen to keep a clean sheet in the run-up to the 2018 Commonwealth Games where he will go in as favourite.
Also in the mens shot put will be former two-times World Indoor Champion Ryan Whiting (USA), 22.00m thrower Konrad Bukowiecki (Poland) and Australian record holder Damien Birkinhead.
