Dame Valerie Adams' hopes of a fourth Commonwealth Games gold medal are on track after she qualified comfortably at Carrara Stadium on the Gold Coast.
Contesting her fifth Games, but just six months after the birth of daughter Kimoana, Adams needed just one effort to better the automatic 16.50m standard.
The double Olympic champion's 18.52m was a season's best in just her fourth competition of the year.
Second place overall went to Canadian Brittany Crew on 17.50, while Trinidad and Tobago's Cleopatra Borel was just 4cm behind, with the pair set to provide Adams' main competition in Friday's final.
On the track, Angie Petty missed out on the 800m finals, with the difficult qualifying criteria meaning she had to finish in the top two of her heat or grab a spot as one of the two fastest losers over the three heats.
Racing against Olympic champion Caster Semenya of South Africa, Petty looked sharp over the first lap, but couldn't make up lost ground over the last 400m and finished fifth.
Semenya won in 1m 59.26s, with England's Alexandra Berll second in 2m 00.11s.
Petty's 2m 00.62s was the seventh-fastest over the three heats, with two slower runners qualifying ahead of her by virtue of finishing in the top two of their heat.
