Watch the extended interview: Grace Millane's mother Gillian sits down with Newshub

Grace Millane's mother Gillian has sat down with Newshub to talk about her mission to climb Mount Kilimanjaro in honour of her daughter and late husband David.

The murder of her daughter Grace sparked international news after the British tourist disappeared in December 2018 while in Auckland on her OE.

Her body was found in bush in the Waitākere Ranges a week after she was last seen at a central Auckland hotel. A 27-year-old man - who had been seen on CCTV footage entering an Auckland hotel with Millane -  was found guilty in November 2019 and sentenced to life in prison with a minimum non-parole period of 17 years. 

But the Millane family's struggles didn't end there with Grace's father David dying two years later of cancer.

Gillian told Newshub the decision to climb Mount Kilimanjaro in honour of her daughter and her husband is a deeply personal journey, saying it helps her get out of bed every day.
