McBride (17) stroked the New Zealand quadruple sculls that won the bronze medal at the world junior championships at Plovdiv.
Her goal is to move further up the podium at next year's world junior championships in Lithuania.
She demonstrated her class at the Otago rowing championships in the heat at Lake Ruataniwha yesterday.
McBride destroyed the field in the open women's single sculls when she beat Lisa Owen (Southern RPC) by 12 seconds, in a time of 8min 08.57sec.
This race brought out a maturity in McBride and she showed an understanding of the right moment to go for the kill in a race.
She teamed with her sparring partner Hannah Duggan to finish second in the open women's double sculls behind the Southern RPC combination of Lisa Owen and Tessa Young.
The Southern RPC combination clocked 7min 34.25 sec and the younger Otago pair were just three seconds behind in 7min 37.67sec.
McBride and Duggan were joined by Anna O'Leary and Claudia Grave and they finished third in the open women's quadruple sculls.
Anna O'Leary is one of the promising younger scullers in the province and she demonstrated her talent by finishing third in the girls under-17 single sculls in 8min 41.84sec.
Elder brother Jack, also a talented sculler, has teamed with Eachann Bruce, from Wanaka, this season.
They demonstrated their class by coming from behind in the last 300m to snatch a last-gasp win in the men's club double sculls.
They pipped the Alexandra combination of Simon Smith and Doug Cryer at the post with a time of 6min 59.83sec. Alexandra was timed at 7min 00.55sec.
Bruce and O'Leary were named crew of the day for their skills in this race.
They were joined by Daniel Hobson and Alex Yarnall and came third in the men's club quadruple sculls in 6min 48.20sec.
Jack O'Leary was runner-up in the club single sculls in 7min 39.66sec and Simon Smith (Dunstan Arm) was third in 7min 41.45sec.
Conditions at Lake Ruataniwha were perfect for the two-day regatta. A record number of 950 rowers competed.
''The heats on Saturday lasted for 12 hours,'' Rowing Otago administrator Sonya Walker said.
''It was the longest day in the history of the Otago championships.''
It was a good regatta for crews from Wanaka. Jack Porter and Riley Bruce won the boys under-15 double sculls in 7min 47.19sec and Anna Watson-Taylor came second in the women's club single sculls.
Watson-Taylor was also runner-up in the girls under-18 single sculls in 8min 51.42sec and Caitlin Buist (Otago University) was third in 8min 58.77sec.
Buist was joined by Nicola Shanks and the pair came second in the women's club double sculls in 7min 50.56sec.
Nicholas Jackson and Jarrod Wellman (Wanaka) won the men's under-19 coxless pair in 7min 23.34sec. The Fred Strachan-coached North End crew of Jack Waddell and James McNicol was third in 7min 25.96sec.
The Dunstan Arm girls under-15 double sculls of Ella Galletly and Eirlys Bond beat Waihopai by 17 seconds in a time of 8min 15.06sec.
They also won the girls under 16 double sculls in 8min 19.50sec.
The women's masters single sculls was won by Imogen Coxhead (Port United) in 3min 59.17sec from Mish Harrison (Wanaka, 4min 06.44sec) and Helen Drijfhout (Otago, 4min 10.12sec).
