The Zombie Apocalypse is shuffling towards Dunedin.
A 5km obstacle race around Ross Creek in which participants flee a ravenous zombie horde is the brainchild of Averil Pierce.
Ms Pierce was searching the internet for fundraising ideas when she found zombie runs had been devoured across the United Kingdom.
So the idea of a Dunedin day of the undead was born.
The Chatbus charity hoped to raise more than $10,000 from the inaugural event, which would go towards an additional bus and counsellor, she said.
The mobile counselling service operated with two buses and two counsellors, and worked with children at 10 primary and intermediate schools around Dunedin.
In the Zombie Apocalypse, participants would face obstacles while trying to prevent zombies taking one of their three ''life'' tags.
Ross Creek would remain open for the Sunday, May 18 event, but signs would warn unsuspecting users what to expect, the Chatbus founder said.
New Zealand Army personnel would also provide assistance on the day.
Fundraising manager Aaron Smith allayed any concern about the zombies getting carried away.
''Our zombies have been trained to go for tags, not necks,'' he said.
