Nyika said he went through a period of soul searching over lockdown, which ultimately led to him finding his purpose.
"Covid's obviously shaken the whole world up in one way or another. I had the blues coming out of lockdown because I realised there's no foreseeable future for me in amateur boxing.
"I felt like I didn't really have a job, have a purpose. As an athlete, my purpose is to be constantly improving who I am. Being able to make this decision to progress my career, it's been tough but it's also exciting.
"It's one of the only things keeping me sane and driving me forward at the moment."
The 25-year-old is excited to show the Kiwi public what he's about on February 27.
"I know that this is one of the biggest events in New Zealand boxing history. I'm aware that people have been anticipating my professional debut and I'm excited to give the people what they want to see.
"I feel like I've done my time and I've been humbled by the sport – I've had injuries and setbacks. But I can also appreciate the love that I receive from my supporters from New Zealand. And I think I'm only going to use the crowd to boost me and to continue on that pathway forwards."
