Dirty needle accidents like that suffered by a Papamoa toddler, are "extremely rare" says Tauranga Hospital medical director of emergency services.
Dr Derek Sage said he had never seen one in Tauranga in all his years at the hospital.
His comments come after the parents of Aurora Archer, 17 months, found their little girl with a dirty needle hanging from her arm after a visit to Papamoa Beach
Ziggy and Callan Archer were swimming and collecting tuatua at Papamoa Beach on Saturday afternoon with Aurora and other family members.
"As well, anyone who witnesses any suspicious or concerning activity is encouraged to phone police," the spokesperson said.
