After her journalism career - which spanned about 15 years - Ms Campbell started her own public relations company, Cathy Campbell Communications.
Yesterday family and friends paid tribute to a woman they described as warm, kind, generous and completely selfless.
In a statement sent to the Weekend Herald, Salizzo said his wife "made the sun shine".
Presenter Susan Wood, who worked alongside Ms Campbell for many years, said she could not say enough good things about her long-time friend.
"The thing I'm going to remember about her is her absolute kindness and her goodness and her decency ... She was always interested in what was going on in your life."
A service to celebrate Ms Campbell's life will be held at 11am on Wednesday at Sacred Heart College in Glendowie, Auckland.
