The power duo threw season bests against their international rivals at the annual Christchurch Big Shot competition.
Adams threw over 18 metres in what she labelled her "season's best," despite falling behind Canadian Brittany Crew for second place.
Tom Walsh took out the men's division with a staggering 21.65 metre throw. He said he still felt like he sat back on the shot put and didn't have much power.
Walsh and Adams said they have turned their focus to next month's Commonwealth Games.
