The victim was yet to be formally identified but police warned those responsible it was "only a matter of time before we arrive on your doorstep".
The comment came two days after the death of the man who was found with serious injuries outside the Flaxmere Tavern.
A scene examination continued over Monday night and police expected to remain there for the remainder of yesterday and into the evening.
Officers said items of interest were found near the tavern, which remained closed while the investigation was carried out.
Detective Senior Sergeant Marty James was continuing to appeal for people with information which could assist the investigation to come forward.
"There are people in the Flaxmere community who know who is responsible for this man's death," James said.
"We want those people to step up, and get in touch with us at the earliest opportunity.
"They can do that anonymously via Crimestoppers if need be."
"And I have a message for the person or people responsible as well:
"Police have a large investigation team working on this case and it is only a matter of time before we arrive on your doorstep. It would be in your best interests to come to us before we come to you."
•Anyone with information was asked to contact police on (06) 831 0700 or to call Crimestoppers anonymously on 0800 555 111.
