New Zealand's women's bowlers led the way into the medal rounds on day four of competition, with Jo Edwards and the four chasing gold in Glasgow.
Edwards had to come from 7-3 down after seven ends to win her second match in a row against Norfolk Islands' Carmen Anderson 21-17.
The Manchester 2002 pairs gold medallist had beaten Anderson 21-16 in their morning clash (local time) and eventually pulled away in her last-eight match after leading just 12-11 after 18 ends.
But Anderson went down fighting, reducing the gap from 20-13 to 20-17 before the Nelson bowler sealed the victory.
She will next meet Northern Ireland's Catherine McMillen for a place in the final and a guaranteed medal.
The women's four advanced to the semifinals in dominant fashion, dispatching Zambia 16-5.
Selina Goddard, Amy McIlroy, Val Smith and Mandy Boyd dictated terms and will face Malaysia in the semifinals.
The experienced Smith had earlier told Fairfax Media the Kiwis had adjusted well to the slow greens in Glasgow after lengthy preparation at home and warm-up matches in Cardiff and near the current venue.
"The greens are still running a little quicker than we expected, but that's working out fine for us," Smith said.
"There's some lines wearing into the greens that you can follow, but if you miss them by just a little bit, sometimes your bowl can go a long way off and make you look a bit silly.
"Some greens have a lot more draw than others too."
The two NZ men's teams in action in the first half of the Games programme both missed out on the last four.
The men's triples team went down 19-17 to South Africa - bowing out with their first loss in six appearances on the Kelvingrove greens after they went through their qualifying group with a 5-0 record.
Tony Grantham, Shannon McIlroy and Ali Forsyth picked up three shots on the first end but fell behind 6-3 before a five on the eighth end gave them the lead again.
They soon squandered that advantage when South Africa picked up a four to lead 11-8, but scores were tied at 13-apiece with six ends to play. The South Africans pulled ahead but a four to NZ on the penultimate end saw them trail just 18-17, only for their rivals to hold on.
Blake Signal and Richard Girvan, in the men's pairs, went out when hosts Scotland inflicted their second defeat of the day on the Kiwis.
After suffering their first loss of the tournament earlier in the day 19-11 to Paul Foster and Alex Marshall, NZ bowed out 25-9 to the red-hot hosts in the quarters.
A bronze medal proved out of reach for the New Zealand para-bowls mixed pairs B2/B3 team.
The visually-impaired Kiwi duo of David Stallard (with director Peter Blick) and Sue Curran (with director Christine Foster) went down 14-11 to their Australian opponents Joy Forster and Tony Scott.
