NSW Swifts midcourter Courtney Tairi has joined New Zealand trans-Tasman netball league team Southern Steel.

The 23-year-old Tairi was born and raised in Sydney but has New Zealand parents, allowing her to play for Steel as a non-import player.

Tairi, who made her trans-Tasman league debut against the Steel at their Invercargill base in 2009, said the prospect of being coached by former Australian international Natalie Avellino was a factor in her switch.

"I used to look up to players like Natalie when I was younger so to train under her is a great opportunity for me," Tairi said.
