Reactions have been amazing for Grace, with Māori singer Maisey Rika even sharing on her social media among the many views that the original Facebook post has had so far.
"Everyone's been saying some of the nicest things. I think, for me, the best thing that people have been saying is that it's changing their views and that they want to learn a version or one from their own region. I'm shocked that I was able to do that.
"I know a couple of people have said I've made history in a way but I honestly just wanted to honour all of the ANZAC soldiers."
Grace wants to be a singer-songwriter and, having recorded with artist Holly Smith recently, she hopes it will be the start of her career.
"I had the most amazing time up in Auckland with her. Thanks to NZ On Air's New Music grant, we were able to get some funding and record four of my own originals.
"You know when you have something, it's your own thing, and then you give it to someone else to do something? It was so cool."
