"After the game the families, wives and girlfriends had a few drinks at the ground - champagne. Then we headed back to the hotel. But it only sank in this morning when Trent and I went out to breakfast. We walked into this Britomart cafe and whole tables started clapping and cheering."
Being thrust into the limelight is new for Smith. Her class of year 5 and 6 at Fairhaven School in Te Puke had only just found out she liked cricket.
"Before the World Cup I put up a poster of the Black Caps in class. One of the children asked if I liked cricket. I said 'yes, and my boyfriend plays cricket'. And one of the class joked and said, 'oh does he play for the Black Caps then?' So I said, 'yes, he does, this is him', pointing to Trent. This student was incredulous and bet another teacher 50 push-ups that it wasn't true. So it was funny because the student ended up doing the push-ups."
Smith was able to harness the class's enthusiasm for their newfound "celebrity" girlfriend with a behaviour chart.
"They get tokens for good behaviour which represent dollars. I have told them that when they earn $100, Trent will come and visit the class."
Smith - whose real name is Alexandra (Gert was a family nickname as it was easy for her younger brother to pronounce) - met the Tauranga bowler two years ago in a Hamilton bar when she was out with her cousin, fellow Tauranga cricketer Daniel Flynn, himself a former Black Cap and now captain of the Northern Districts.
"I knew a little bit about cricket because of Daniel but I didn't know all the rules.
"Now I do, and it is good when a new wife or girlfriend joins as you don't feel that you are the new one."
Smith doesn't mind the term WAG but said the New Zealand wives and girlfriends didn't really think of themselves in that way. "It is not like it is all we do, we either are busy with families or have our own jobs."
Camaraderie is strong among the partners of the "boys" and Smith is particularly friendly with Tim Southee's girlfriend Briar. "Sometimes Briar and I phone each other before a game stressing about what to wear. It was funny as in the Australian game they gave us rules of no singlets or jandals."
As for Trent, Smith says he gets "pretty nervous" before a game. New Zealand Cricket do not have rules that the team have to spend time apart from partners so Smith will be with Boult in Melbourne.
In the cafe Smith was waiting to hear from Boult before he boarded his plane yesterday. She will join him tomorrow with his parents and brother Jono.
She thinks they will calm their nerves shopping.
"Trent likes to shop, he likes surf shops, Huffer, so he likes shopping in Melbourne.
"In fact we often shop around a game ... I think it is a way he calms his nerves, he buys so many white shirts and striped shirts."
Boult also takes two good luck symbols with him says Smith, "this huge book Shantaram, it has so many pages but he has only read 11 but he carries it to every match. And also his grandma's necklace. She has passed away but they were very close."
The other thing that really boosts Boult's performance is the crowd.
"He really thrives off the crowd, the cheers, the support, it really does drive the boys."
