Kiwi come home: Taonga return to Ruapehu ancestral forest after 30-year effort

In the cool, green cathedral of native forest within the Ruapehu District’s Karioi Rāhui, the call of the kiwi is returning. Last week, local iwi Ngāti Rangi welcomed home 10 taonga (valued) western brown kiwi at Tirorangi Marae before releasing the juvenile birds into forest at Rotokura and Rangataua – whenua (land) their ancestors roamed a generation ago. It marks the first step in a major translocation effort that will see 40 kiwi returned to iwi whenua over the coming year. For those involved, the moment has been decades in the making. “There were kiwi within the Karioi Rāhui [the 5300ha ecological project in southern Ruapehu] before,” Helen Leahy, pou ārahi (te ao Māori leader) of Ngā Waihua o Paerangi Trust, said. “But in 1996, the numbers were so small that they were no longer considered viable.” What followed was a long, deliberate rebuilding – not just of bird numbers, but of relationships. Local iwi worked alongside the Ngāporo Waimarino Forest Trust, Ngāti Hikairo, Sanctuary Mountain Maungatautari and others to strengthen fragile populations through shared breeding and genetic diversification. The original founding kiwi were introduced to Maungatautari in 2005. “Different birds were shared across sanctuary sites to help keep populations more genetically viable and diverse,” Leahy said. That collaboration is now bearing fruit. The birds released in the Ruapehu District last week are descendants of the small founding group – just eight pairs and three chicks – whose lineage has been carefully nurtured over two decades. Today, more than 3000 kiwi live within the predator-free sanctuary at Maungatautari, itself home to more than 730 species. From that abundance, the next phase was always clear: return. “We’ve built up a gene pool and the genetic diversity within that gene pool,” Wiki Papa, of Pōhara Pā, who travelled with the birds from Maungatautari, said. “The aim was always to build a thriving kiwi population and then share the taonga with iwi in other spaces.” Leahy acknowledged the leadership of Sanctuary Mountain Maungatautari, the Maungatautari Ecological Island Trust, Save the Kiwi and Te Papa Atawhai in their work to protect and grow the kiwi population and to then support their release to safe places in the wild. More than 600 kiwi have been translocated across the motu (land) in the past three years alone. For Ngāti Rangi, this return carries particular weight. “It’s been a big, special day for our people – it’s been terrific,” Fred Clark, kaihonohono a rohe/environmental and relationship adviser for Ngā Waihua o Paerangi, said. “This first Ngāti Rangi-led kiwi translocation marks a milestone achievement that has been an aspiration of our people for many, many years – probably a few generations.” Clark said the first foundation kiwi for Maungatautari were from Ngāti Hikairo and Ngāti Tūwharetoa, and the second group were from the Waharangi block in the Waimarino area, provided by the Ngāporo Waimarino Forest Trust and Pipiriki township. The third group came from Taranaki to widen the gene pool and strengthen the genetic profile. “All the western brown kiwi that are in Maungatautari are descendants of those foundation birds,” Clark said. “The manu [birds] that have come back to us today are descendants of the whenua who are returning home as per their genetic profile.” Fred Clark leads the Ngāti Rangi kiwi restoration project. Clark said Ngāti Rangi wanted to remember those who facilitated the mahi (work) and the first engagement – “the likes of Uncle Don Robinson, Uncle Paora Haitana [known as Uncle Baldy] ... Uncle Boy Cribb and Aunty Geraldine Taurerewa”. Looking to the future, three local rangatahi (youth) – Lucas Kumeroa, Taiaroa Haddon and Kino Haitana – are already training to become certified kiwi handlers, part of a wider effort to ensure the iwi can sustain and protect the population into the future. “That’s the vital point,” Leahy said. “We need predator control and safe environments – but...
