Patience (17), a pupil at Otago Boys High School, won the gold medal in the 1500m freestyle at the national age group championships at Christchurch.
Patience's gold medal winning time of 15min 45.35sec in the mens aged 17 and 18 grade was 7.20sec faster than Loader's 1993 long course time.
This was an outstanding performance, because Loader went on to win two Olympic gold medals and a silver medal.
His New Zealand record was a personal best time by 10 seconds, and was worth 831 International Swimming Federation (Fina) points.
Coach Andy Adair has been impressed with the dedication Patience has shown since arriving in Dunedin 14 months ago.
‘‘Shane has coped with the heavy training load and is producing world-class times for his age group,'' Adair said.
Patience was the outstanding Otago swimmer at the championships and won six medals - two gold, three silver and a bronze.
His other gold medal came in the 200m butterfly and his silver medals were in the 200m and 400m freestyle, and the 100m butterfly.
Patience left his parents' home in Wellington to join coach Andy Adair's distance squad at the Waves club.
It was a big decision to leave his friends and parents on the Kapiti Coast and come south to a new environment.
The shift to Dunedin is part of his long-term goal to represent New Zealand at the 2010 Commonwealth Games in India and at the 2012 Olympics in London.
He chose to come to Dunedin because Adair trains international Bryn Murphy and has the best distance training group in New Zealand.
Otago swimmers performed impressively at the championships and won 22 medals - six gold, nine silver and seven bronze.
The other Otago gold medallists were Waves swimmers Adam Simpson (400m freestyle) in the boys aged 15 grade and Phoebe Williams (800m freestyle) in the girls aged 15 competition.
Two members of the Otago Swimming Coaching Academy (Osca) also won gold medals.
Matthew Glassford (Alexandra) won his gold medal in the boys aged 17 and 18 grade in the 200m breaststroke in a time of 2min 21.53sec to set a new Otago record.
He broke a provincial record when winning the silver medal in the 100m breaststroke in 1min 06.84sec.
Katie Kenneally (Taieri) won her gold medal in the girls aged 16 200m breaststroke in 2min 42.31sec. She also won a silver medal in the 100m breaststroke in 1min 15.52sec.
The big mover for the Waves club was Simpson, who won his first national championship title. It was his first medal at a national championships.
He also won a silver medal in the 1500m freestyle and bronze in the 400m individual medley in his age group.
The only swimmer trained outside Dunedin to win a medal at the championships was Annabelle Simpson (Queenstown), who captured bronze in the girls aged 17 and 18 50m butterfly in a personal best time of 29.20sec.
The Waves club finished sixth from the 76 competing clubs at the championships.
The national age group championships were changed this year to combine age 13 to 15-year-olds with 16 to 18-year-old youths.
‘‘Last year, Waves was thirteenth in the age category and twelfth in the youth grade,'' Adair said. ‘‘It is a fantastic improvement.''
Brazier said the improvement has come because the Waves club coaches had stepped up the type of training to include more threshold training and dry land work.
Physiotherapist Helen Littleworth has been employed to help with the dry land training.
‘‘Waves swimmers are the first at training in the early morning and the last to leave at night,'' Brazier said. ‘‘This level of commitment has hardened their mental attitude.''
