Lifejackets save lives but an old lifejacket can be dangerous in a water emergency situation.
Coastguard's Old4New Lifejacket Upgrade campaign will be in town in January and Coastguard Whanganui president Garry Hawkins says local boaties should get their jackets checked.
"We do annual checks on our jackets and I would suggest everyone do the same.
"It is worth checking them even if they are new to make sure they will inflate properly in an emergency."
The Old4New van is travelling New Zealand and will be at Coastguard Whanganui, 7 Wharf St on Friday, January 4 from 8am until noon.
