New year's festivities proved too much for one man at a Timaru supermarket.

Shoppers at Pak N Save in Timaru were given an unexpected dousing with wine after New Year's festivities proved too much for one man.

A 20-year-old man from Uruguay was arrested at 5pm on Saturday after he walked into the supermarket, opened a bottle of wine, and sprayed customers- yelling "happy New Year's" as he did so.

Senior Sergeant Dylan Murray said the man was arrested, but no details were available about any charges that may have been laid.
