Coxhead (53) joined in the action nine years ago.
Her children are no longer involved in the sport but Coxhead has become one of the powerhouses of masters rowing in New Zealand.
She won three gold medals at the national masters championships last season and continued her superb form at the Dunstan regatta at the weekend.
Coxhead won the single sculls convincingly and then stroked the Port United quadruple sculls and coxless fours to wins.
The other members of her crew were Michelle Johnson, Karen Thompson and Alison Howlett. The talented Lucy Geddes (Dunstan Arms), who won a bronze medal in the girls under-15 four at the Maadi Cup at Lake Karapiro last season, easily won the girls under-16 single sculls.
Two other scullers who joined her on the podium at the Maadi Cup, Ella Galletly and Sydney Cook, were in the crew that came second in the under-16 quadruple sculls. The other member of the crew was Nikita Parker and the cox was Brylie Thompson.
The Columba College crew of Amber Beaumont, Genevieve Walker-Radich, Lucia Graham, Kendra Crawford, Simone Reid, Sasha Holland, Sophie Anderson, Brittany Spark and cox Margot Darling won the novice eight. Four North End crews qualified for the A final of the boys under-15 double sculls, Mitchell Anderson and Quinn Hawthorne winning the event and Mike Freeman and Nic Walding finishing second.
Lili Sabonadiere and Bireana Shea (North End) won the girls under-16 double sculls.
The strong Otago club dominated the sculling events. World junior silver medallist Jack O'Leary showed his class to win the men's under-18 and the open single sculls.
Rebekah Pitcaithly won the women's under-18 single sculls and fellow Otago sculler Emma Winders the women's open single sculls. Anna O'Leary and Winders won the women's open double sculls, then paired up with Otago University rowers Caitlin Buist and Nicola Shanks to win the women's open quadruple sculls. Shanks and Buist were second in the women's open double sculls.
