In 2007 Ms Johnson opened Gallery 57 in Shannon as an outlet for her own hand-painted canvas and jewellery designs. The success of Gallery 57 led her to open a second Shannon store, Oosh Giftware that also became an outlet for her own clothing line, Oosh La La.
Oosh La La garments are designed by Ms Johnson and made in Levin and she had since opened a third Shannon store, Oosh La La, that exclusively carries the clothing line.
She opened a fourth Shannon store, For Frocks Sake in late 2010 and had also since opened three more shops in Woodville, and a sewing factory and retail outlet in Napier.
Ms Johnson also had written and published The Book and co-hosts a Saturday morning show on 92.2 MoreFM Manawatu.
Ms Johnson said she was "now taking Oosh on the road" as part of a two-hour one-woman show and comedy performance.
"I believe that New Zealand women are too hard on themselves and need to work on building confidence... there's nothing more sexy than a confident woman."
