Snehal Pradhan
Ex-India seamer on BBC Test Match Special
I think spin is the way to go with Atapattu. She likes pace on the ball.
And it's going to be the pace of Lea Tahuhu to open proceedings for the White Ferns, bowling from the Prenderville Stand End.
Two splendid anthems, two splendid teams.
Captain Sophie Devine - who knows this ground well, having played for Western Australia for the last couple of winters - summons her team for a quick huddle before they take the field.
Time for "God Defend New Zealand", the stirring, bilingual NZ anthem. There are a few Kiwi flags fluttering around the Waca, too.
There is a line of mascots standing in front of the players. Very sensibly, they've been dressed in dark blue floppy sunhats. Not much cover around at the Waca when the sun's out.
Players walking out for the national anthems.
Sri Lanka's anthem is just starting, so you've got time to make a cup of tea.
Nicky Shaw
Ex-England all-rounder on BBC Test Match Special
I'm looking forward to a good game. Sri Lanka have lost a lot of games in these tournaments - but they've just beaten England in a warm-up game, inside 12 overs.
New Zealand: Sophie Devine (capt), Rachel Priest (wk), Suzie Bates, Maddy Green, Katie Perkins, Katey Martin, Amelia Kerr, Hayley Jensen, Leigh Kasperek, Lea Tahuhu, Jess Kerr.
Sri Lanka: Chamari Atapattu (capt), Hasini Madushika, Harshitha Madhavi, Anushka Sanjeewani (wk), Shashikala Siriwardena, Nilakshi de Silva, Ama Kanchana, Kaveesha Dilhari, Sugandika Kumari, Udeshika Prabodani, Achini Kulasooriya.
This is the second game in Group A, by the way - the first was India's win over Australia yesterday.
Want to see those highlights again? Oh, go on then...
BBC Test Match Special
Test Match Special are up and running again on BBC Radio 5 Live Sports Extra and via this page - with ex-England all-rounder Nicky Shaw, player of the match at the 2009 World Cup final, and former India seamer Snehal Pradan on summariser duty again.
Sri Lanka have a significant duck to break today. They've faced New Zealand seven times in full T20 internationals, and the White Ferns have won on all seven occasions.
The Waca is always traditionally seen as a fast bowlers' paradise - but it can also help the spinners too. Shane Warne always enjoyed bowling there, and even Monty Panesar took a Test five-for there.
Spin also seemed to be the way to go in the first game - West Indies sent down 14 overs of twirlers, while leg-spinner Suleeporn Laomi was Thailand's most effective bowler.
But you can bet Sri Lanka won't relish facing the pace of Lea Tahuhu, one of the fastest bowlers in women's cricket, charging in with the new ball. All food for thought.
Sri Lanka captain Chamari Atapattu: "I trust my batting unit, it's good for batting first. We're playing good, we beat the world 50-over champions but this is a new game. There are a lot of Sri Lankans in here, we will try to play positive cricket."
New Zealand captain Sophie Devine: "We want to make first use of this pitch. We're excited. We want to get out there and make a mark on the tournament.
"To be captain, leading a fantastic group of athletes, it makes it that much more special.
"We certainly think we have the team to win it. Every team is so strong, so we take each game as it comes."
New Zealand win the toss and field first.
Welcome back - it's Mark Mitchener back with you now, as our live text merry-go-round continues with New Zealand v Sri Lanka.
As we await the toss at the Waca, you can read Amy Lofthouse's report on West Indies' win over Thailand, and take a look at the undoubted champagne moments from the early game - two terrific run-outs from some electric Thai fielding.
Remember, this was just the first part of a double-header. Sri Lanka meet New Zealand on the same ground in a little over an hour, and we'll be back for that.
More from West Indies captain Stafanie Taylor: "For Thailand it is very special. If they keep playing, they will get better. The way they are playing, they might cause an upset."
Thailand captain Sornnarin Tippoch: "We are happy. We played well. We wanted to get a score of around 120.
"The West Indies fast bowlers bowled short balls, that is something we have to learn about.
"Today isn't our day, but we have things to work on.
"We have strength in our bowling and fielding. We will try our best in every game. We have been waiting for this moment for a long time. We are so happy."
West Indies captain Stafanie Taylor, named player of the match: "I was felling good with my bowling, but with the bat I felt like I couldn't get the ball off the square. I just felt I had to stay there and get the team over the line.
"A lot of their bowlers we don't know, so we had to take time out to get used to the pitch."
