Fire burned along about 10m of a hedge in front of the Mulligan Cafe on the corner of Chelmer and Cross Sts, in Oamaru, yesterday.
The Oamaru Volunteer Fire Brigade was called out at 9.11am and took about 20 minutes to put out the fire. Apart from the hedge, only minor damage was caused to the children's playground at the cafe.
Chief fire officer Steve Couper said the fire could have been caused by a cigarette or a spark under the hedge. CCTV footage at the cafe could show the ignition source.
