Heritage roses are back at Dunedin's Northern Cemetery after hundreds were poisoned two years ago.

About 500 roses were damaged in the twenty sixteen incident.

They included some memorial roses planted by families of those buried at the cemetery in the eighteen hundreds.

It turned out the roses had been sprayed with herbicide.

The Dunedin City Council conducted soil and foliage tests, but it was never conclusively proved who had done the spraying.

The council says the damage had upset a lot of people, so the council had worked with Heritage Roses Otago, and provided two thousand dollars for the group to replace them.

Graves across the cemetery are now sporting fresh woodchips and new plantings.
