Auckland teenager Olivia McTaggart could be New Zealand's next pole vaulting star after shattering Olympic bronze medallist Eliza McCartney's New Zealand under-17 record in Auckland on Saturday.

The 16-year-old cleared the bar at 4.22m, 11cm better than McCartney's previous mark and 22cm better than her previous personal-best, set in Auckland a week ago.

Like 19-year-old McCartney, who holds the NZ women's record (4.80m) and captured the hearts of the nation when she won Olympic bronze in Rio in August, McTaggart is coached by Jeremy McColl.

McCartney was one of the first to congratulate McTaggart after the effort, posting a photo alongside the 16-year-old pocket rocket and McColl on social media.

"This amazing lady Olivia McTaggart jumped 4.22m at the age of 16!!! Smashing my record of 4.11m, so exciting to see our sport growing so fast. Well done Jeremy for cracking the pole vault formula," McCartney posted.

McTaggart, who won the national under-20 title in Dunedin in March with a 3.70m effort, also took to social media after breaking the record and significantly improving her personal-best.

In addition to posting that she was "stoked" and that it hadn't sunk in, she promised that there was more to come.

That can only bode well for the sport McCartney and McTaggart could star in for years to come.
