Tributes to the man have been left on social media - with family and friends voicing their disbelief at his death.
The man’s name has been suppressed due to the ongoing police investigation and because his family asked that his name not be published.
Police confirmed they were conducting inquiries on behalf of the Coroner.
Detective Inspector Glenn Baldwin said: “Police are limited in further comment on this matter and we note the Coroner has issued an interim non-publication order.
“It is important to emphasise that our inquiries are still in the early stages, with further pathology tests and results still pending,” he said.
Baldwin said the man was not involved in importing or distributing the contaminated beer “in any way”.
“We are conscious that at the very heart of this matter is a man’s family who are grieving the loss of a loved one. As such police strongly advise against any speculation around the circumstances or the victim in this case,” Baldwin said.
Police earlier said it was unlikely the distinctive blue and red cans have been sold over the counter or online - “however, part of the shipment may have been given away or passed on between associates,” Detective Inspector Chris Barry said.
It was believed the beer was not available to be purchased in New Zealand and no other brand is involved in the shipment.
“Police ask anyone who might be in possession of a can of ‘Honey Bear House Beer’ to not drink it and to contact police immediately by phoning our 105 phone service quoting the file number 230310/6793,” Barry said.
Anyone that might have further information regarding the product is asked to also contact police on 105 or Crime Stoppers anonymously on 0800 555 111.
