Two quick wickets for New Zealand as Bree Illing has Harshitha Samarawickrama caught behind before Sophie Devine removes Kavisha Dilhari in the next over.

Sri Lanka are still going for it, though, with Nilakshi de Silva coming in and powering a couple of boundaries.

But Illing strikes again in her next over as Hasini Perera falls in near-identical fashion to Samarawickrama, edging behind off the back foot.

Sri Lanka don't bat as team as some teams at this World Cup but the intent is still there as Piumi Wathsala comes in at seven.

With 10 overs to go, Sri Lanka have positioned themselves very well to really kick on and have a big finish.

They got 47 runs without losing a wicket in the past 10 overs, have eight wickets in hand and Harshitha Samarawickrama and Hasini Perera's partnership is now worth 53.

New Zealand are going to have their wits about them in the last stage of the innings, both with ball and in the field, to prevent Sri Lanka pushing up towards 250.

Sri Lanka continue to build a good platform from which they will hope to really kick on from late in the innings.

Harshitha Samarawickrama has come in and is going along nicely at a run-a-ball, while fellow left-hander Hasini Perera is ticking over pretty well, too.

They'll want to increase the run-rate before too long and New Zealand could do without the sort of misfields that allowed Samarawickrama to find a boundary through Jess Kerr's legs off Melie Kerr's bowling.

The younger sister is not best impressed...

Both Sri Lanka openers gone now as Rosemary Mair pegs back Vishmi Gunaratne's off stump.

The right-hander had played patiently but was trying to up the ante with Chamari Athapaththu gone.

It's lovely ball from Mair, nipping away just a tad to beat the bat and clatter into the timbers with Vishmi stuck on the crease.

Conditions looks ideal for the seamers right now, the floodlights have been on for a while and there are leaden skies overhead.

A few of those clouds look pretty ominous and the wind has picked up but, crucially, it is still dry for now.

A big wicket for New Zealand, just after they had put down another catch.

The century opening partnership comes up as Vishmi Gunaratne is dropped for a second time!

She charges Melie Kerr and tries to hit over mid-on. The elevation isn't quite there but Suzie Bates can't hold on to the grab above her head.

Another let off for Vishmi but there is no such luck for Chamari Athapaththu in the next over.

The skipper tries to flay Sophie Devine over the off side but is caught by Maddy Green at deep cover for 53.

Hasini Perera, another left-hander, comes in for Sri Lanka.

The Sri Lanka captain reaches her 20th ODI half-century from 67 balls.

Top stuff from Chamari Athapaththu as she cuts Sophie Devine away for four to get to 49 and then chips into the gap at mid-wicket for two to bring up the fifty.

If the left-hander can stay out there for another 20 overs or so then Sri Lanka will be in a great position.

In terms of setting a platform, Sri Lanka could hardly have asked for better in the first part of this innings.

Chamari Athapaththu took advantage of the fielding restrictions in the powerplay and since then, she and Vishmi Gunaratne have steadily accumulated against the New Zealand spinners.

Vishmi cashed in on a drag down from Eden Carson for the first boundary since the ninth over.

But there have been a couple of scares for Vishmi.

In the over prior, the right-hander successfully overturned an lbw decision as UltraEdge showed she got a faint edge on Melie Kerr's googly.

Then in the 20th, she thumped the ball back at Sophie Devine but the White Ferns skipper couldn't cling on to the return catch.

New Zealand have managed to slow Chamari Athapaththu down since the end of the powerplay.

No boundaries for Sri Lanka in the past five overs with spinners Eden Carson and Melie Kerr beating the bat a couple of times each.

Chamari Athapaththu is really getting into her stride, she have six boundaries through the covers already.

The Sri Lanka captain is so dangerous on the drive and, as ever, really holds the key to her side's innings.

It's been more of a struggle for Vishmi Gunaratne at the other end but Eden Carson helps her out with a wide full toss that the Sri Lanka right-hander can slap away through point for four.

The fifty partnership comes up in the last over of the powerplay. A very handy start for Sri Lanka but Carson almost breaks the stand with a beauty that turns just past Athapaththu's outside edge.

A fairly watchful start from Sri Lanka with New Zealand seamers Bree Illing and Rosemary Mair keeping things tight.

But it looks a good surface and Chamari Athapaththu has shown a couple of signs that she is in the mood today.

She got off the mark with a gorgeous drive second ball and drilled another drive through extra cover in Illing's latest over for her second boundary.

Anthems done and they're ready for the off.

Sri Lanka openers Chamari Athapaththu and Vishmi Gunaratne stride out to the middle as New Zealand's Bree Illing prepares to bowl the first over.

After losing their first two games, New Zealand can get themselves right back in the mix for the top four with a win today.

Meanwhile, Sri Lanka will leapfrog the Kiwis if they can secure their first victory of the tournament...

Sri Lanka: Chamari Athapaththu (c), Hasini Perera, Vishmi Gunaratne, Harshita Samarawickrama, Kavisha Dilhari, Nilakshika Silva, Anushka Sanjeewani (wk), Piumi Wathsala, Sugandika Kumari, Malki Madara, Inoka Ranaweera.

New Zealand: Suzie Bates, Georgia Plimmer, Amelia Kerr, Sophie Devine (c), Brooke Halliday, Maddy Green, Isabella Gaze (wk), Jess Kerr, Rosemary Mair, Eden Carson, Bree Illing.

Chamari Athapaththu calls "heads" and heads it is, Sri Lanka are going to bat first.

New Zealand skipper Sophie Devine says they planned on bowling first anyway.

The Women's World Cup group stage has reached the halfway point now and co-hosts Sri Lanka are still looking for their first win.

Today they take on a New Zealand side with just one win to their name and in a real fight to make the semi-finals.

Both sides then will be delighted that it is currently dry in Colombo and will be hoping that the rain forecast for a little later stays away.

Right, let's get to the news from the toss...
