British paddler Rachel Cawthorn was nearly a second adrift in second place, clocking 2:00.476, while China's Yu Zhou finished in 2:01.028.
Carrington picked up where she'd left off in the afternoon session, with the world and Olympic champion winning her heat and semifinal in the K1 200m to qualify fastest for tonight's final.
She clocked 44.140secs in her heat, then a sharp 42.960 in the third semifinal, with Inna Klinova (Kazakhstan) the next fastest in 43.652. Linnea Stensils (Sweden) and Yu Zhou won the other two semifinals respectively.
The other New Zealand paddler at the third world cup, Titahi Bay's Marty McDowell, finished eighth in the A final of the K1 1000m, fading at the end but giving coach Gordon Walker plenty to work on.
"Three regattas in three weeks has certainly been tough but at the same time, very revealing," Walker said. "Marty knows the areas he has to work on and if he can string some good consecutive weeks of training together, he has a chance come worlds."
Carrington's 200m final will start at 8.39pm (NZ time) tonight.
