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.
The womens shot put will be headlined by twice Olympic gold medallist Valerie Adams, on a comeback for the Commonwealth Games after the birth of her daughter in October.
Canadas Brittany Crew, who beat Dame Valerie 18.42m to 18.06m last Friday in Christchurch will be in the field, along with another from the Canadian Games team, Taryn Suttie and American Brittany Smith.
Kiwi Torie Owers, third behind Crew and Adams at Friday's Big Shot in Christchurch will also compete on Sunday.
McCartney drew a big crowd on Sunday for the Vertical Pursuit on Federal Street in central Auckland - and she wowed the enthusiastic spectators, clearing 4.90m, the seventh highest womens vault of all time.
The Rio 2016 bronze medallist is in excellent form heading into her first Commonwealth Games and is keen to improve on her NZ record of 4.82m in an official competition before too long.
Joining her in the womens pole will be Canadians Alysha Newman and Anicka Newell, on their way to the Commonwealth Games, while Morgan Leleux (USA) makes up the internationals and they will be joined by 17 year old Imogen Ayris, winner of the New Zealand senior womens title two weeks ago in Hamilton.
