Road breakdown staff are being kept busy at beaches around the country, going to the rescue of absent-minded holidaymakers.
The Automobile Association says callouts to popular coastal spots are soaring, with almost 60 per cent involving flat batteries, starting difficulties, or keys locked in cars.
"Because they're relaxed and in holiday mode, people quite often make mistakes they wouldn't normally make," said AA Roadservice national manager John Healy.
"Our service officers and contractors have accessed a number of locked vehicles to retrieve car keys that have inadvertently been left in the boot after people have dropped their keys inside while they're unloading bags or getting beach gear and picnic baskets out."
The top trouble-spot for holidaymakers with car trouble is Mission Bay in Auckland, where the AA has logged 56 callouts since December 21.
