Sarah "Sass" Warner (previously Burton, Connelly and Coutts) is a fictional character on the New Zealand soap opera Shortland Street.

[3] Lucy Lovegrove was working in a bookstore in Melbourne when she received the offer to play the role of Sass,[4] an experience she referred to as, "literally one of those 'my life has changed over night' situations.

I had six days to pack up my house, quit my job, say goodbye to my flatmates, fly to Canberra to say bye to my family and get to New Zealand.

The characters of Frank, Finn, and Sass were introduced in 1993 during a whodunit storyline, revolving around sperm donation to the head nurse, Carrie Burton.

[10] He, Whiting, and Lovegrove referred to Galvin as "dad" onset and Patrick believed, "he's a top bloke and really acts like a father figure to us.

[11] When the shooter puts the gun to Finn's head he says "Mason says Merry Christmas" shortly after the gunman is pushed out of a window to his death by Chris.

[11] Desperate to have children but with no stable partner in her life, Shortland Street clinic's Head of nursing Carrie Burton (Lisa Crittenden) accepts sperm donations from nurse Steve Mills (Andrew Binns), Guy Warner (Craig Parker), Dr. Hone Ropata (Temuera Morrison) and Dr. Chris Warner (Michael Galvin); refusing to disclose whose sperm she used.

Carrie gave birth to triplets during good friend Meredith Fleming's (Stephanie Wilkin) leaving party and named them, Frank, Finbar, and Sarah.

Declan proved to be a useless father and ended up fleeing the country to escape criminal associates he had, leaving Steve to be a surrogate parent.

In November 1995 Chris visited Carrie and the triplets so that he could introduce his father Bruce (Ken Blackburn) to them before he succumbed to terminal cancer.

After having a one-night stand and not willing to pursue a relationship with a mysterious woman named "Sass", TK Samuels (Benjamin Mitchell) was shocked to realise she was Finn Connelly's (Lukas Whiting) triplet sister and long-lost daughter of Chris Warner.

Sass quickly made an impression due to her direct and efficient manner, securing herself a position as Chris' executive assistant and making it clear she believed he had failed the triplets as a father.

She began to casually date Curtis Hannah (Jayden Daniels) but whilst preparing for Finn's wedding, received news that Hawks was in fact alive after months in hiding.

She decided to leave Ferndale to care for Hawks in Turkey following the loss of his leg, and bid farewell to Chris and her family.

Sass would reappear in person in 2023, working with her father and Monique Strutter (Courtney Louise) on finances to reopen Shortland Street hospital after it burnt down in a fire at the end of 2022.

[3] Actor Michael Galvin (Dr. Chris Warner) named the triplet's returns in 2016 as his favourite storyline, noting the "fun" the co-stars have on set.
