A police spokesman said police were seeking three men in relation to the death.
They did not believe firearms were involved and had not recovered any weapons.
Detective Senior Sergeant Warwick McKee, of the Wellington Criminal Investigations Bureau, said the property had been cordoned off and was now the subject of a scene examination today.
"Police would like to hear from any members of the community that may have any information in regards to any persons involved in this matter,'' he said.
