Foreign Affairs Minister Murray McCully says a memorial service for the 202 people who lost their lives in the Bali bombing a decade ago was a "moving reminder" of the tragedy that affected so many nations.

Three New Zealanders - Jamie Wellington, 31, Mark Parker and Jared Gane, both 27 - were killed in the terrorist attack on the popular tourist spot of Kuta on October 12, 2002.

Eighty-eight Australians, 32 Indonesians and 24 British citizens were also killed in the blasts which hit the Sari Club and Paddy's Pub.

A further 240 people were injured.

More than 1000 people gathered at an Australian-led memorial service at the Garuda Wisnu Kencana Cultural Park on Friday afternoon (NZT) to remember those who lost their lives.

Mr McCully represented New Zealand, alongside New Zealand's ambassador to Indonesia David Taylor.

Eight New Zealanders who were injured or suffered lasting trauma from the attack lit a candle to remember the victims.

"I was grateful for the chance to pay respects to New Zealand victims and their families, and to acknowledge once again the terrible losses suffered especially by Australia and Indonesia," Mr McCully said.

"In the 10 years since this event, Indonesia has come to grips with the problem of home-grown terrorism," he said.

Bali-based New Zealand nurse Stephanie Breen, who was awarded an Order of Australia Medal for helping the injured, said the service would be a time of reflection for her.

She told TVNZ she would never forget what she saw at the hospital a decade ago.

"I opened the doors and there were just people lying everywhere on the floors and I swear my heart just fell to the floor."

The New Zealand government last week offered to help pay for families of those killed in the explosion to fly to Bali for the commemorations, but the Ministry of Foreign Affairs and Trade told NZ Newswire none had taken up the offer.

Australian Prime Minister Julia Gillard, former prime minister John Howard and Leader of the Opposition Tony Abbott also attended the ceremony.
