The 24-year-old pace bowler forced her way into the England ODI team earlier this month. She previously played two international twenty20 games for her country in 2013.
The right-armer has picked up two wickets in four ODIs and will make her debut for the Sparks when Otago starts its campaign with a twenty20 match against Central Districts at the picturesque Pukekura Park this afternoon.
"It will be a good start to my New Zealand adventure," Langston said.
"I think the [England] head coach will be checking up on results, so hopefully if I do well over here it will stand me in good stead for the World Cup in England next year."
Langston, who describes herself as "fairly quick", mostly takes the ball away from right-handers but has a few useful variations she was reluctant to reveal much about.
"I don’t want to give away all my secrets."
She honed her bowling skills against her three brothers in the backyard and joined Essex as a 10-year-old. She played for Essex age group teams before eventually making the senior side, but transferred to Yorkshire last season.
"I made a big move. Unfortunately, Essex had gone down a couple of divisions and I wanted to try and play first-division cricket.
"It was a tough decision leaving the county that I’ve played with since a youngster."
Her stint with Yorkshire did not go as hoped. She played "a couple of games" before getting injured.
"It is a bit embarrassing. I missed a ball in the field and it cracked me on the ankle and it turned out it was broken."
Langston made her return for the Loughborough Lightning in the Super League and played alongside New Zealand’s Sophie Devine.
The Lightning made the semifinal but lost to the Western Storm.
Langston played alongside White Ferns and Otago spinner Leigh Kasperek while at Essex. The pair kept in touch and it was that connection which helped Langston land a playing gig in New Zealand.
"I asked [Kasperek] if Otago was looking for any overseas players and they were keen and that is how it came about.
"I think it will just be a really good experience playing in a different domestic competition. I’ll get to match my skills against some different players and see how it goes."
The Sparks, led by White Ferns captain Suzie Bates, have a very useful side and are targeting making one of the two finals. Bates has been a key figure in the team for more than a decade. Wicketkeeper-batsman Katey Martin is also vastly experienced and the next most important player in the batting line-up.
Spin duo Morna Nielsen and Kasperek are both proven international performers and can be relied on to have a big impact domestically. Kasperek is a danger with the bat as well.
American Shebani Bhaskar has joined the squad this year. The 22-year-old all-rounder has played international cricket for the United States. She is predominantly a top-order batsman but will bowl some seam and may even take the gloves if needed. Following today’s twenty20 fixture, Otago and Central will play back-to-back one-day games.
