Cass Square is expected to be out of bounds for most of the rugby season after taking a hammering from two big events in succession, in the wet.
Large patches of newly-sown grass were killed off from the trampling of 5800 pairs of feet during the wet Wildfoods Festival, and hundreds were back on the square on Sunday for Children's Day. The new turf was also tested by the South Island Marist Rugby Tournament on March 4.
The Westland District Council had planned to carry out remedial works costing $10,000 after Children's Day, however, more rain caused more damage as the turf turned to mud in places. Gumboots or no footwear at all were the order of the day due to the muddy conditions.
Council field inspections officer John Bainbridge said the volume of people and vehicles driving over it had flattened the grass further, affecting the drainage.
"The top surface is now totally sealed off because it's been compressed by the thousands of people walking over the grass and vehicles driving all over it while wet. It's going to require some extensive rehabilitation and it probably won't be usable for most of the rugby season," Mr Bainbridge said.
