The finals of the Maadi Cup will be held tomorrow and Saturday.
The annual national high school rowing championships, held at Lake Ruataniwha, Twizel, began on Sunday, with a parade through the Twizel township.
Rowing officially began on Monday.
The cup is run by the New Zealand Secondary School Rowing Association and Rowing NZ.
More than 2283 athletes from 120 schools have been competing in the week-long event.
The South Canterbury schools competing are Craighead Diocesan School, Roncalli College, Timaru Boys’ High School, Twizel Area School and Timaru Girls’ High School.
The regatta alternates between Ruataniwha and Lake Karapiro in Waikato.
The two big final days will be held tomorrow and Saturday, with Sunday morning a “spare” day if any events are postponed due to weather or other reasons, a Rowing NZ spokeswoman said.
