Just after 5pm, the woman described as “the love of his life” armed herself with a 10cm-long kitchen knife.
She entered the bathroom and stabbed Willis 22 times.
Matthew Mawkes, a long-time friend of Willis, spoke to the ODT detailing the loss felt by the New Zealand film community.
“It was very shocking news. It was hard to understand ... hard to grasp,” Mawkes said.
“Mark was eccentric. He was very loving, gentle and had a wicked sense of humour.
“He was a movie buff and much loved by everyone who knew him ... much more so than I ever think he realised.”
Born and raised in Dunedin, Willis worked alongside well-known film-maker Robert Sarkies, becoming a “really, strong close collaborator” and friend for over 30 years.
“There was a real gentleness to Mark, which I find highly ironic, considering the way his life ended ... which has been very difficult for all of his many friends throughout the country,” Sarkies said.
Willis contributed his love for storytelling and special effects to Sarkies’ well-known production, Scarfies.
“You could really rely on him to create extraordinary things.”
“I saw him sitting outside a couple of weeks before with his head in his hands, looking kind of desperate,” they said.
Mawkes said despite having a few months to “deal with it”, he did not feel the need to find an explanation for what happened.
“For me personally, at the moment, I am just remembering Mark.
“We are finishing the movie in his memory and that is what we are focused on.”
Sarkies echoed the sentiment, conveying a sense of sadness rather than feelings of anger.
“The end comes to us all at some point, but the last minutes of his life should not define his life ... It isn’t all about how you die, it should be about how you live.”
