A crowd of about 2500 watched Olympic and world shot put champion Valerie Adams (Auckland) finish her southern hemisphere season with a New Zealand all-comers and resident record of 20.54m.
It was Adams' 11th New Zealand championship shot put title.
Adams also broke her own Caledonian Ground record of 19.05m, set in 2005, by 1.49m.
Jacko Gill (Auckland) added another age-group record by beating the world record for 16- and 17-year olds with the 6kg shot with his 21.34m.
It was the first world record at the new Caledonian Ground since it was opened in 1999. Gill now holds 10 world records.
Adams added 21cm to the record set at the Auckland championships last month. Her national record of 21.07m was thrown in Thessaloniki, Greece, in 2009.
Five of her six attempts were over 20m and two broke the old record of 20.33m. Her sequence was: 20.09m, foul, 20.54m, 20.20m, 20.27m, 20.40m.
"I came out today to try and break my own resident and all-comers record," Adams said. "I'm happy with my series and pretty stoked to throw 20.54m.
"Competing in New Zealand is always hard to get out for, but if I can do it here, I can do it anywhere."
Adams competed in just three meetings during her time back in Auckland. She won the Auckland championships with 20.33m and threw 20.55m in Sydney.
She returns to her base in Switzerland this week to train with her coach, Werner Gunthor, who won world shot put titles in 1987 and 1991 and was third at the 1988 Olympics.
"My coach will be happy," she said. "He wanted me to throw 20.50m before I went back."
Adams has been training by herself since returning to New Zealand but has sent video analysis of her training and competition back to her coach.
"I've been doing it on my own and I'm sure my coach will be happy," she said.
Adams was in a happier frame of mind than last year when she was attempting to change her technique to get greater distance.
"It was [bad] last year. I'm super happy now. I was happy to get all my throws over 20m today.
"I always love competing in front of my home crowd."
Adams does not peak during the New Zealand season. Her main focus this year is on competition in Europe and peaking for the world championships in South Korea in August.
She will have two months of hard base work when she returns to Switzerland.
"There will be lots of lifting, lots of throwing and lots of heavy stuff," Adams said.
