She said the little boy who found her was given the honour of naming him.
He decided to call the chick "Happy Feet" after the Warner Brothers animated movie.
She said she put Happy Feet on a feeding tube of vitamin supplements and just two months later she was walking again.
Happy Feet needed fluids put into her to flush her kidneys out and rehydrate her.
She required a syringe to eat fish and long periods of rehabilitation in the pool.
"She's come a long way, we were very surprised at how well she's done.
On first arrival Happy Feet was "severely underweight".
She has since put on about 500 grams thanks to Ms Flynn's care.
An aquarium worker estimated Happy Feet was about one year old.
She's a mixed breed blue penguin.
Although regularly brought hawks, swans and shags, this was the first penguin Ms Flynn had nursed.
Happy Feet will soon visit Massey University to undergo a blood test and ascertain if there was an underlying cause to her illness.
From there she will be taken into the care of the National Aquarium Napier before hopefully returning to Tangoio Beach.
