Trent Keegan, 33, was found bashed to death in a ditch in Nairobi in May.
Recently two men charged with assaulting and robbing the New Zealander were acquitted on the charges. No one has been charged with his murder.
Last night a spokesman for Foreign Affairs Minister Murray McCully told the Taranaki Daily News that Foreign Affairs was seeking further information from the Kenyan authorities in regard to the court case and whether an appeal or further investigations were being undertaken.
Mr Keegan's family has called for the New Zealand Government to honour its promise and fully investigate his unsolved murder.
His sister, Nikki McKinnon, has just returned with her Australian cameraman husband from London, England, to live in New Zealand.
She told the newspaper her mission now was to support her parents -- her mother lives in New Plymouth and her father in Auckland -- and to fight to get the Government to assist in unravelling the mystery of his death.
So far the family had been disappointed with the Government's response.
"We're wanting to hear from the New Zealand Government on their promise to investigate further pending the outcome of the Kenyan inquiry," she said yesterday.
Shortly after Trent's death, former prime minister Helen Clark had called for a thorough investigation, she said.
"They issued a press release and we never heard from them again," Ms McKinnon said.
Mr McCully declined to comment on the verdict or Kenyan justice system saying it would be inappropriate at this time, his spokesman said.
