"Penguins are nesting at this time of year and are known to travel quite far inland at times. They are a lot more athletic than they look," Denise Fastier, DoC senior ranger of biodiversity, said.
Little penguins nest in rocky areas and usually roam further in alone.
"They are a marine animal not freshwater, so it is best not to encourage them to spend time in pools," Haydon said.
DoC recommends leaving penguins alone and keeping dogs away from their nesting areas.
The little penguin is an at-risk declining species due to habitat loss, human intervention and predators such as cats, dogs and ferrets.
According to IUCN, there are 470,000 little penguins in Southern Australia and New Zealand.
Haydon recommends leaving any little penguin found inland alone and calling 0800 DOC HOT so a biodiversity ranger can assess the situation.
"If someone finds a kororā in an unusual location, it's best to leave them be and give them space unless there's a reason for concern such as an injury or risk to the bird's wellbeing," Fastier said.
"Only DoC staff and those holding a relevant Wildlife Act authority are permitted to interact with native wildlife."
The woman who spotted the penguin could not be contacted for comment.
