The multi-skilled Tuivaiti, 29, grew up in the Far North before being lured to Auckland as a 14-year-old where she has been showcasing her netballing talents ever since.
During those years, Tuivaiti has gone on to forge a formidable shooting partnership at domestic and international level with Maria Tutaia but is excited by the prospect of teaming up with talented Pulse shooter Ameliaranne Ekenasio (nee Wells) and building another equally forceful pairing.
"I'm really excited about the new challenge of not only playing netball in a different area of New Zealand and rekindling the passion, but also learning about myself away from family and friends," she said.
With the pair recently married, Tuivaiti's husband Jim has just returned to Italy where he will start his second season of professional rugby with the Calvisano club.
"It is a bit tough as we are newly-weds and it's hard being apart but we knew what we were getting ourselves into," she said.
"We don't want to give up our respective codes just yet as we both believe we've still got more in the tank."
That's a sentiment echoed by coach Yvette McCausland-Durie who is delighted to welcome the experience and ability Tuivaiti will provide the Pulse's attack end.
"Cathrine has one of the best accuracy rates in the business and a defining skill set which will prove invaluable," she said.
"She has an abundant natural talent which can only be enhanced and built on while her experience and leadership abilities will be great assets for our younger players to learn from."
Tuivaiti joins Sheridan Bignall, Karin Burger, Ameliaranne Ekenasio, Claire Kersten and Whitney Souness as confirmed signings for the 2017 edition of the Pulse.
