Harry Warner (previously Thompson and Thompson-Warner) is a fictional character on the New Zealand soap opera Shortland Street who first appeared onscreen in May 2002.

In 2001 the shows producers decided to undergo a story that saw Toni Thompson (Laura Hill) give birth prematurely during the soap operas 10th anniversary.

[1] It was decided the role of Harry would be recast in 2006 after Directors struggled to convince 3 year old Campbell-Ross to film "naughty boy" scenes where he broke a sandcastle.

[10] In 2023 Shortland Street underwent a "new-era" of the show with 6 new characters arriving to "mix things up" as part of a medical trainee storyline.

[14] In 2001 Toni Thompson (Laura Hill) fell pregnant but it was not clear who the father was as she had been sleeping with both Adam Heywood (Leighton Cardno) and Chris Warner (Michael Galvin).

She gave birth several months prematurely in May 2002 and it was not until Rachel McKenna (Angela Bloomfield) had the babies DNA tested that Chris was revealed as the father.

Harry caused trouble for Chris and Toni the following year, when his tantrums climaxed in him biting Huia Samuels (Nicola Kawana) hand.

Harry was devastated months later when Toni died and struggled to come to terms with Chris' succession of girlfriends – going so far as to force him to break up with Brooke Freeman (Beth Allen).

During Halloween 2013, Harry stopped breathing and lost his heart beat for 45 minutes after drinking a potion made of several garden weeds, including foxglove.

However, after Chris used his chief executive officer position at the hospital to register prolonged CPR, Harry survived without brain damage.

However Pixie was diagnosed with bone cancer and Harry supported her through the following treatment but was devastated when she succumbed to pneumonia shortly after the two had confessed their love.

Harry began to date Lily Flores (Zoe Fong) but landed in huge trouble when Chris caught him sending sexual images.

Harry returned months later, furious with Chris for hiding his cancer diagnosis, and having accidentally impregnated his homestay sister Zhilan Li (Bridget Wong).

After witnessing Chris payoff his daughter in law Mindy Connelly (Catriona Toop), he disowned him and turned to half-brother Finn (Lukas Whiting) for finances before returning to China.

Zhilan's father arrived and threatened Harry, resulting in Chris attempting to seek custody of Xun to ensure his safety.

Having married Zhilan and separated, Harry frustrated fellow intern Stella Reihana (Tatum Warren-Ngata) with his womanising ways, before the two started a relationship.

It soon became apparent Harry was hiding something from his past in China and became intensely jealous when Stella started seeing Rahu Parata (Zak Martin).

Sabotaging Rahu at work in an attempt to discredit him including by forcing an overdose on a patient, Harry began to struggle with his past when Chris uncovered a strained relationship with Zhilan and Xun from drink-driving in China.

Eventually manipulating Stella into re-entering a romance, she soon started to suspect Harry of murder after discovering Max's missing phone in his bedroom.

Piecing together the facts, she accused Harry of purposely killing Rahu - leading to Police uncovering his false work history.

[8] Co-star Angela Bloomfield (Rachel McKenna) praised Walker for his acting during the 2011 illegal smacking storyline, "Reid did a fantastic job.

[29] Across his 5 different actor portrayals, The Spinoff reviewer Tara Ward noted Harry "has remained consistent in his ability to polarise audiences.

[19] American television host Jimmy Kimmel proclaimed on his late-night talk show that, "I know a hell of a cliffhanger when I see one", before he recreated the scene playing Harry with Alec Baldwin portraying Chris.
