Knowing the implications of what a loss to Jamaica in pool play at the Commonwealth Games could have meant, Silver Ferns' coach Dame Noeline Taurua didn't mind going a little off-script on Monday morning.

The Silver Ferns passed their first major test of the Glasgow Games by beating Jamaica 53-48, which could prove critical in their path to a potential gold medal match.

A loss would have put the Silver Ferns on course for a semi-final against world number one Australia, with the Diamonds expected to top their pool in the netball programme.

The heavyweights from Pool B were both desperate to avoid a semi-final meeting with Australia, who beat England by 19 goals in the opposite group on Sunday night in a statement performance.

Jamaica beat the Silver Ferns twice at the 2023 Netball World Cup to deny them a medal in Cape Town, and Taurua said Monday's win over the Sunshine Girls was huge for their confidence.

"Knowing that we are progressing in the right direction. It was tough out there, defensively we knew that they were going to be strong. We had a bit of a quiver on the way but to come out with the win is awesome," Taurua said.

To win gold in Glasgow, the Silver Ferns will have to play seven matches in just nine days.

Taurua said given the rigours of that schedule, every player will need to have their loads managed and be given a break at some point.

"With all of them, we know what our loads are, which is why with our first game [against Scotland] nearly everybody got on. I went a bit rogue today in regards to our loads to get that win but thank goodness we've got the day off tomorrow."

Taurua had intended to give Catherine Hall, who is coming back from foot surgery, some time on court today, but with Burger and Kelly Jackson combining well, she resisted putting the exciting defender on court.

"She will feature when the time is right, I have no issue about her being on but I also know that we've got to make sure we put her in a good position and in an environment that we know she'll thrive.

"Putting her out there today under such huge pressure, sometimes it's a balancing act, but it's also difficult when you've got Karin and also Kelly turning over a lot of ball."

Taurua started Kate Heffernan at centre, Maddy Gordon at wing attack, and sprung a bit of a surprise by starting Mila Reuelu-Buchanan in the unfamiliar position of wing defence.

Kimiora Poi came into wing attack after half-time with Gordon going to the bench.

Gordon came into centre for the final quarter, with Kate Heffernan going to the bench with the game still on the line.

"It's a fine balancing act but how we keep the stability in our team, but also know we've got a few more days of games, so we had that in our mind but I thought with giving Maddy that time off court and to introduce fresh legs, I thought worked really well."

Reuelu-Buchanan usually plays centre/wing attack but Taurua said her personality suited the doggedness needed at wing defence.

"She's a grafter, she's got the voice, she's like a halfback you know coming out of the scrum, she always chats... I thought she played well right through so she warranted to stay out there."

Captain Karin Burger, who is a goal defence-wing defence slide, said Reuelu-Buchanan had embraced the challenge.

"She's done such an amazing job learning that position, she's so eager, she's got the mongrel, she's ruthless when she goes out there and just her energy that she brings, she is so impressive and the versatility she brings to this team is amazing," Burger said.

Taurua was pleased with the way the Silver Ferns withstood Jamaica's defensive line, which is widely recognised as the strongest in the world.

Grace Nweke put up 47 of New Zealand's goals.

Goal attack Georgia Heffernan was playing Jamaica for the first time, and while she only put up six goals, she was responsible for a lot of goals assists.

"We always knew that Jamaica's defence is a power house, so we were expecting that and really pleased by some of our players. I mean Georgia has never played Jamaica so it's a new experience for her, and also the change-up of Kimiora also going in, just giving ourselves some fresh legs and getting a bit of speed."

Captain Karin Burger said they had done a lot of work leading into the game, aware that a win could set them up well for the tournament.

"Even though we had six months of prep for all the teams we are coming up against, we had a big focus on Jamaica, knowing that they were in their pool. We want to finish at the top," Burger said.

The Silver Ferns play their third pool game against Uganda at 6am on Wednesday.
