ACC received 75,000 claims from accidents occurring in the Bay last year, at a to-date total cost of more than $58 million.
Nationwide, New Year's Day was the most common day for accidents of the six days around the two main holiday days.
Around 5000 Kiwis had an accident to end or start the year. The top injury cause was a loss of balance or personal control, follow by a lifting or carrying strain.
Slipping or skidding, being struck by a person or animal, and tripping or stumbling rounded out the top five.
Soft tissue injury was the most common diagnosis, followed by a laceration, sting or a puncture, a fracture or dislocation, or a dental injury. A "foreign body in an orifice or eye" was the fifth most common diagnosis.
ACC spokeswoman Suzanne Muth said the majority of accidents over summer happened in and around the home as a result of falls - with stairs being the most common location.
"It's important to take time to clear away clutter away from underfoot, secure extension cords and rugs, keep thoroughfares well-lit and remind energetic youngsters 'to apply the brakes', especially if you have more folk than usual at home over the upcoming holidays," Ms Muth said.
Ms Muth said DIY and alcohol-related injuries were also common over the holiday period.
Some tips include:
Around the home:
•Point out hazards that you may be familiar with, but which could trip up visitors, eg single steps between rooms.
•Wipe up spills as soon as they happen.
•Put away toys and keep clutter, guests' luggage etc clear of walkways.
DIY:
•Be realistic about your ability - if you can't do it, get an expert.
•Use a safe, stable ladder - always keep three points of contact, eg two feet and one hand, and don't over-reach sideways.
•Make sure you know how to use hire equipment.
•Plan your schedule so you're not rushing to get the job finished at the end of the day, when you're tired and more likely to slip up.
When drinking alcohol:
•Set a limit on your drinking and stick to it.
•Eat substantial food and pace yourself with non-alcoholic drinks.
•Look after your mates.
