"Police [are] still looking for the robbers and [the] community [is] not safe until they are arrested," said the 58-year-old monk.
"They hit me and hurt me even when I told them I have no more money ... they [are] very dangerous."
He gave his three attackers all the cash he had, which was coins from the donation box, but they continued to beat him.
The monk suffered a number of fractures and a serious head wound and had to be taken to Middlemore Hospital for treatment after the August 16 attack.
Master An, who is still nursing a broken arm, said his attackers "took everything from the temple", including his mobile phone.
"I have [been] in and out of New Zealand since 1987, never believe something like this can happen here," he said. "Especially not at temple, because it is my home and also place of peace."
Nancy Pham, a temple volunteer, said the temple members were "in total shock" about the attack.
"We were all really upset and shocked, and angry that people could do this to hurt Master An," she said.
The Herald understands the temple land was donated by a local Vietnamese businessman, and more than $1.3 million has been spent on developments.
Police spokeswoman Kimberley Mathews said police did not believe other monks or Buddhist temples would be targeted.
They believe burglary was the motive.
