Prime Minister Helen Clark said while the actions of the Bali bombers were heinous the Government did not support them being executed.
It was reported on Friday that three Indonesian militants convicted for their roles in the 2002 Bali nightclub bombings appeared to have exhausted all legal avenuesto avoid the death penalty.
The three Islamic militants - Amrozi, his brother Mukhlas alias Ali Ghufron and Imam Samudra - have been on death row since 2003, when a Bali court sentenced them to death for their roles in the nightclub bombings that killed 202 people including three New Zealanders.
Miss Clark was asked at her post-Cabinet press conference for comment.
"The New Zealand Government does not support the death penalty under any circumstances," she said.
"Clearly these men are guilty of heinous crimes and those crimes, in any jurisdiction, would justify them (getting) very serious penalties available under law but the New Zealand Government will not and does not support the death penalty."
On Friday Australia's Prime Minister Kevin Rudd, whose country lost 88 citizens in the blasts, said while his centre-left government opposed the death penalty, it would not intervene.
"In the case of foreign terrorists we are not in the business of intervening on any of their behalves," he said.
Indonesia does not make public the timing and exact location of executions.
The men are being held in a maximum-security jail on Nusakambangan island off Central Java, hundreds of kilometres from their families who live in East and West Java.
