New Zealand athlete Valerie Adams added another gold medal to her shot put stockpile with a commanding win at the world indoor championships in Poland.

Adams dominated the eight-woman final on Saturday, winning with a best distance of 20.67m.

It eclipsed the 19.94m achieved by German silver medallist Christina Schwanitz. Both throwers produced their longest throws in the fifth round of six.

Adams, 29, was never challenged in winning a third world indoor crown, adding to her four world outdoor titles and two Olympic Games gold medals.

The Aucklander landed all of her five legal throws beyond the 20m mark, a feat nobody else could achieve once.

She produced a foul in the third round, blighting an outstanding sequence that read 20.06m, 20.41m, 20.10m, 20.67m and 20.16m.

Her career best in indoor competition is 20.98m, set in Zurich last August.

It was just her second competition of the year, having won with a best of 20.19 at a meet in Christchurch two weeks ago.

Adams' triumph follows the surprise bronze medal in the men's shot put to 22-year-old Tom Walsh, who was competing in his first major international meet.
