Isle Rietberg (Logan Park) won the senior girls shot put that was the glamour event of the Otago secondary schools athletics championships on Saturday.
It is the only athletics event in which New Zealand has a world and Olympic champion.
The girls in the throwing events were attempting to walk in the footsteps of Valerie Vili.
Vili was the inspiration for Rietberg (18) and runner-up Nicole Bradley (Queens) as they strove to break the record.
Bradley equalled her own record with a put of 10.45m but Rietberg went one better and broke the record with her three throws 11.50m, 11.63m and 11.15m.
She beat the record by a massive 1.18m in her first season using the 4kg implement.
It placed Rietberg third on the New Zealand junior women's ranking list for the shot put this season.
The two girls ahead of her are on scholarships at United States universities and the distances were achieved overseas.
Rietberg is an exchange student from the Netherlands who is spending a year studying at Logan Park High School.
In Holland, she is coached by Joop Tervoort, who has coached a silver medallist at senior world championships.
She has joined Raylene Bates' throwing squad while she is in Dunedin.
When she returns to the Netherlands, Rietberg will study medicine at Groningen University in her home town.
Her immediate task is to improve her distance by a metre at the Otago and Southland championships at Invercargill next Saturday to beat the record of 12.56m that Judith Knapp (Menzies College) set in 1984.
Rietberg and Bradley dominated the senior girls throwing events on Saturday, with the Dutch visitor also winning the javelin (30.53m) and Bradley winning the discus (34.65m) and hammer throw (34.61m).
Rebekah Greene (St Hildas) ran from the front and won the senior girls 1500m in a record time of 4min 38.23sec.
It reduced the record that school mate Louise Harvey set last year by a massive 16 seconds.
Greene (16), who had spent last week on a school tramp on the Abel Tasman track, led the field through the first lap in 69 seconds and two laps in 2min 25sec and kept moving away from the field.
In the end, she won by 21 seconds from Shauna Pali (Kavanagh) with Bella Bloomfield (Otago Girls) third in 5min 00.85sec.
William Scorgie (Otago Boys) used different tactics to win the senior boys 800m-1500m double.
In the 1500m, he trailed Alex Gorrie (Kavanagh) by 15m down the back straight, but sprinted strongly round the final bend and caught him down the straight to win narrowly.
Scorgie was timed at 4min 07.30sec and Gorrie at 4min 07.91sec.
The time by both runners was just short of the record of 4min 07.20sec set by junior international Max Smith (Kings) in 2001.
Scorgie adopted a different approach in the 800m when he attacked at the bell and won going away from Ben Jowsey (Kaikorai Valley) in a record time of 2min 00.98sec.
It beat the old record of 2min 01.57sec that Bevan Stevens (Otago Boys) ran in 2003.
Toby Flett (Otago Boys) won the senior boys 100m (11.98sec) and 200m (23.33sec) double.
He was pushed hard by school mate John Gilmour in the 100m.
Gilmour got a flier and led at 50m and Flett needed to dip at the tape to win the title.
Gilmour was timed at 12sec.
Lauren Wilson (Queens) won the senior girls sprint double in the 100m (13.19sec) and broke the record with her 200m time of 26.22sec.
Ashleigh White (Blue Mountain College) won the girls under 16 javelin (26.71m), shot put (10.09m) and discus (26m).
Libby Jones, a boarder at St Hildas from Wanaka, won the girls under 14 hammer throw (22.93m), discus (27.98m) and shot put (9.16m).
She is the granddaughter of former Otago All Black Tuppy Diack, who was at the ground cheering her on.
Twelve athletes broke individual records at the championships.
The others went to Megan McPhail (Waitaki Girls) in the girls under 16 200m (26.63sec), Toby Batchelor (John McGlashan) boys under 16 3000m (9min 25sec), Andrew Whyte (South Otago) senior boys 400m (51.34sec) and Chris McNoe (Otago Boys) boys under 14 800m (2min 13.20sec).
There were 30 AWD athletes competing at the championships and they broke three records: Ricky White (Sara Cohen) boys 200m (26.69sec), Nikita White (Otago Girls) girls 100m (17.54sec), David Takarei (Kings) boys 400m (1min 10.77sec).
There were also two 4 x 100m relay records.
The Otago Boys senior team of Tim Lawrence, John Gilmour, Toby Flett and Kane Russell ran 43.91sec.
The Columba College senior girls team of Renaye Flocton, Biddy Skerten, Sophie Napper and Libby Cochrane ran 51.91sec.
