And South African import Lenize Potgieter will ply her trade in Australia next season.
But the Steel will be able to call on the services of Trinidad and Tobago shooter Kalifa McCollin.
McCollin has signed with the franchise and will partner the 1.92m Jen O'Connell in the shooting circle.
O'Connell has re-committed to the team after spending most of this season watching from the sideline with Potgieter preferred at goal shoot.
McCollin, who is 1.8m tall, has impressed in the UK's Vitality Superleague for the past three years. Her superior accuracy earned her a place in the competition's All Stars team this season.
The 23-year-old sports psychology student is excited to embark on the next chapter in her netball career.
"I was buzzing when the Steel called. I told my dad first because, between him and my mom, he's more calm," she said.
"My mom overheard the conversation and before I could say anything she started crying tears of joy because she knows how hard I work.
"I'm very excited to be joining the Southern Steel. They're a top team so it'll be great to now be a part of such a strong unit.
"I have a tag line that I've taken with me throughout my career - Netball is Art, the court is my canvas - and that's something I always remember when I set foot on the netball court."
Selby-Rickit has been a loyal campaigner since joining the team as a 19-year-old in 2011 and admits it was a difficult decision to leave.
"I've called the South home for a number of years now," she said.
"I've had so many people influence me with different coaches and players.
"I have literally grown up here and made some of my closest friends, so leaving is very difficult but I feel like the time is right to make a change.
"I'm going to miss the Steel a lot - the franchise has been like family to me and I've made so many memories with this club.
"I've been really fortunate to be able to play with my sister and my best friend for so many years. Not many people get to do that week in and week out and call it a job, so I'm really grateful.
"I really want to say a big thanks to the Steel community. They have been a huge part of the reason I love it so much here.
"I've lived a long way from home since I left school. But it's been made easier by the way in which they've taken me and my family in."
The move was not just netball focused, as Selby-Rickit was eager to spread her wings.
"For me it's about growth and seeking something new to get out of my comfort zone. I've always loved Christchurch as a city and there's a lot of new and exciting things happening there so I'm looking forward to moving north."
