She is now calling on her hometown supporters to vote for her in the Multimedia Head to Head contest.
As part of the challenge, Tyson gave a TV interview and spoke about why she's proud of her Māori culture.
"In New Zealand, there is sometimes a negative perception about indigenous people and so being able to use my voice to showcase people in a positive light is so rewarding and being able to showcase the wonderful things that they are doing," she said.
"Back home we have doctors who are creating groundbreaking research to help thousands of people within our communities.
"We have sportswomen and sportsmen winning top international awards overseas.
"We have so many people within our communities creating small community projects who may be helping people struggling, who may be homeless for example, and so being able to use my voice to raise awareness on this creates so much positivity within my country."
Supporters can vote for Tyson by liking her Jessica Tyson - Miss World New Zealand 2018 Facebook page before voting closes at 10pm, Friday November 30, NZ time.
The Miss World final will be held in Sanya City, China on December 8.
