McCartney claimed silver in the women’s pole vault to match the earlier efforts of Kiwi shot putter Tom Walsh.
The vaulter cleared a best height of 4.8m, the same height as gold medallist Molly Caudrey, of Great Britain.
Caudery, McCartney’s training partner, won gold on the countback, but both looked strong before the Olympics and would have been pleased with their performances.
United States vaulter Katie Moon secured bronze with 4.75m.
"It hasn’t sunk in yet", McCartney said.
"I am just really stoked to have been a part of such a neat competition. Now I have this medal, I’m so happy."
Kiwi sprinter Zoe Hobbs finished fourth in the women’s 60m final and set an Oceania record with her time of 7.06sec.
On Saturday, Walsh won silver in Glasgow to secure his fifth consecutive indoor championships medal with his best throw of 22.07m.
World and Olympic champion Ryan Crouser set a mighty championships record of 22.77m to win gold.
But it was another quality display from the Kiwi, who toasted his 32nd birthday by becoming the most decorated male shot putter in the history of the world indoor championships.
Fellow Kiwi Jacko Gill produced his career-best effort at a senior championship to finish fifth with 21.69m.
Italian Leonardo Fabbri claimed the bronze medal with 21.96m.
"It was nice to grab the whole set but I wanted a different birthday present", Walsh said.
"I felt I gave myself a chance every round and that’s all I can ask for.
"This year is an Olympic year and an important one to get right. I feel like I’ve learned a few things this year. I’ve thrown really well — I’m just saving one for later in the year."
Maia Ramsden made a memorable debut in the black singlet by easing into the final of the women’s 1500m in a national indoor record time of 4min 6.51sec.
The 21-year-old Harvard University student was happy to slot in at the back of the seven-strong field for the first couple of laps before slowly making her way through the field, and on the penultimate lap she moved past experienced Australian runner Linden Hall to move into third spot.
While US indoor 1500m champion Nikki Hiltz won the heat in 4min 3.34sec to top the qualifiers into the final ahead of Great Britain’s Georgia Bell (4min 4.39sec), Ramsden, 21, maintained her composure to claim a comfortable third well clear of Hall (4min 9.83sec).
The performance lowered the previous New Zealand indoor record of 4min 11.68sec, set by Lucy van Dalen in 2012, and also bettered Ramsden’s PB of 4min 8.6sec, set when striking gold at the 2023 NCAA championships.
"I’m so happy. It has been an incredible experience so far and today extends that by two more days", Ramsden said.
A slick move on the inside on the final lap helped George Beamish ease into the final of the men’s 1500m as the 27-year-old Kiwi produced a composed display to place third in 3min 39.17sec.
