Think decapitation when zombies come knocking.
''Cut the head off - that's a good start,'' sensei Phil Davison said.
Mr Davison said he would be demonstrate how to kill a zombie at the DunDEAD festival at Otago Museum today and tomorrow.
He would use ''science of perception'' to teach how to kill a zombie horde.
The best weapon to bring to the fight was an attitude to adapt because if you had a plan, you were as good as dead, Mr Davison said.
''If you can't cut the head off, maybe you can cut a leg off and then you can run faster than a zombie can hop.''
DunDEAD spokeswoman Ann Cronin said the inaugural two-day festival would explore zombie pop culture and brain health.
The festival talks would encourage scientific inquiry, she said.
''Zombies used to be people, so their science is our science.''
A world record attempt in the Octagon tomorrow night of a zombie thriller haka - similar to the scene at the end of the movie Boy - was postponed after a Dunedin woman claimed it could be culturally insensitive.
Ms Cronin said she had been too busy to seek approval from local Maori so the record attempt was postponed to next year.
A Michael Jackson thriller dance would replace the record attempt, she said.
Associate Prof Poia Rewi, of Te Tumu: The School of Maori, Pacific and Indigenous Studies, said the organisers were right to cancel the record attempt without completing an ''assurance process'' to deem it appropriate.
''That's the safe way to make sure they don't get any negative kickback,'' Prof Rewi said.
To begin the approval process, Ms Cronin should contact the Dunedin City Council cultural adviser, he said.
