While most people enjoyed a long weekend, Doug Blakie spent Waitangi Day preparing a submission on why the man who murdered his daughter should stay in prison.
It was the 12th anniversary of the discovery of Lisa Blakie's body, a day Mr Blakie always finds miserable.
But to spend it focusing on her killer was heartbreaking.
Lisa, 20, was killed on February 2, 2000, in the Castle Hill Basin area in North Canterbury.
Four days later, a group of men on a Waitangi Day fishing trip found her body submerged under a 104kg boulder in the Porter River off the Arthurs Pass Highway.
Lisa was hitchhiking when Timothy David Taylor picked her up on the outskirts of Christchurch, stabbed her eight times and strangled her to death.
In 2002, a jury found Taylor guilty of murder, and he was sentenced to life in prison.
Now, 10 years on, he is eligible for parole - something Mr Blakie has dreaded. A hearing is scheduled for the end of the month.
"It's very difficult. But no matter the time, it still hurts. Birthdays, the anniversary of Lisa's murder on the second, the anniversary of the day her body was found on Waitangi Day. It's always a miserable Waitangi Day for us," he said. "Obviously we've been expecting it [the parole hearing]. It's a mixture of sadness, but then there's determination to do the very best we can to keep this bastard inside.
"As a family, we were bitterly disappointed with the Crown for not pursuing preventive detention, which was an option. Now as a family we have to, at such an early stage, push for continued prison for him."
Taylor was also convicted of kidnapping and aggravated robbery offences in 2001. In 2003, he was convicted of the 1983 rape of a teen.
"I'm determined to speak my mind and also to look the Parole Board in the eye and square up to them," said Mr Blakie.
He also wants to ensure the board knew the full effect Taylor's callous crime has had on the family.
They suffered a second cruel blow when Lisa's stepsister Lynda took her own life in 2007.
The sisters were very close and Lynda struggled to cope with her murder. She died with a picture of Lisa in her hand.
At the time, her mother Vicky said the 23-year-old had never recovered from Lisa's death.
"She was just very, very sad all the time. She used to cry a lot. She couldn't come to grips with it, couldn't understand why anyone could do anything so horrible," she said.
This week, Mr Blakie said his daughter's murder had a lot to do with the pain Lynda suffered in her life, though there were other factors.
"Lynda absolutely adored Lisa; they were very, very close," he said.
"We did lose two girls, and that's it. He did have some involvement in that. I will be mentioning her name in my submission."
Mr Blakie said the parole hearing brought back all the pain he felt when Lisa was killed.
He had to identify Lisa's body at the Christchurch morgue after she was found, and he said the upcoming hearing reminded him of the harrowing experience and the court case that followed.
"It does dredge up emotions, flashbacks and all those things."
He said Lisa's mother Phillippa and sister Rebecca never got the chance to say goodbye to her properly, which they still found hard.
"It was awful and abhorrent for them to fly over from Australia to Christchurch, knowing full well they were coming to see Lisa dead. They were unable to view her because of the state the body was in. They didn't have a chance to, as any parent wants to, physically see their loved one and say goodbye."
Lisa's brother Geoff Blakie and stepsister Nicky were also struggling 12 years on from Lisa's death.
Sensible Sentencing Trust spokesman Garth McVicar said victims' families lives were "thrown into a spin" when they were notified of upcoming parole hearings.
"They keep a mental note of when it will come up, but they dread the day they get the notification," he said.
"The hearing could be in six weeks or three months. It seems like a short time from our perspective, but for them when they are in that space, it drags out. It's sad and frustrating to watch what these families go through."
Mr McVicar said the parole system - under which offenders, once eligible, appear once a year - caused families anxiety and tension and resulted in sickness and even death.
"I don't think the human body is made to endure that kind of stress. Most families can deal with the initial crime. They deal with it and they want to be able to put it behind them as much as possible. But with the current parole system, and having to go up against it year after year in some cases, that is impossible for them.
"Under the current system, the offender is the only person who has a choice. The victim doesn't have a choice, their family doesn't have a choice. The whole system is designed around the offender."
