Haberdashery was a great way for people to connect, she said.
"This will not only be great for our community groups but it will be a great way for people on their own to meet new people and join circles - to be a part of a community and develop community cohesion.
"Greerton has a great community but there are a lot of people on their own in society, and they don't want to go to a pub or play a sport, especially older people, but they want to be a part of something in the community where they can feel valued and support each other," she said.
Knitting would start in February and installation to decorate Greerton would take place on June 24.
Mrs Power was hoping to get about 100 keen yarn bombers, including schools and retirement villages, to create coverings for the trees.
If anybody wanted to learn to knit or crochet there would be casual classes on a Tuesday night at Greers Restaurant and Bar starting in February.
Organisations which would benefit from the yarn bombing would include Shakti, Citizens Advice Bureau, the Blind Institute, Cancer Society, Te Tuinga Whanau - Support Services Trust and Grief Support Services.

Don't think knitting that's cool? Ryan Gosling learnt to knit from "old ladies" while filming Lars and The Real Girl in 2007. He later said it was one of the most relaxing days of his life and is now known to knit odd pieces on film sets.
