Their reliance on specific roosting trees, however, makes them particularly vulnerable to habitat loss caused by vegetation clearance and tree felling.<\/p>\n
A significant discovery was recently made at H\u0101pua, a Tuki Tuki Valley property offering boutique accommodation in Hawke\u2019s Bay, where these critically threatened mammals were found.<\/p>\n
Peter Fowler, the kaitiaki (guardian) of H\u0101pua for the past 25 years, became aware of their presence only after his cat brought home a deceased bat.<\/p>\n
Fowler emphasised that the cat had not killed the bat.<\/p>\n
\u201cThe Department of Conservation has examined the bat and believes it was already dead when found.<\/p>\n
\u201dThe discovery highlights the immense value of the remaining forest and bush pockets that still survive in the valley,\u201d he said, <\/p>\n
He described these areas as \u201cthe last strongholds for a species that might otherwise have been lost\u201d.<\/p>\n
Far from the mythical image of blood-sucking creatures, New Zealand\u2019s native bats are gentle, social mammals.<\/p>\n

They prefer to roost in cracks and holes in large native trees, but also use suitable small and exotic trees.<\/p>\n
Following the discovery, Fowler contacted Mark Roper of The Bat Co. Lab in Havelock North. <\/p>\n
As part of the NZ National Bat Survey he established, Roper and volunteers are deploying and servicing bat detectors within a 25km radius of Te Mata Peak, Hawke\u2019s Bay.<\/p>\n
Peter Fowler’s bat sign at Hapua will alert visitors to their presence.<\/p>\n
He said this has led to the identification of a previously unknown bat colony several kilometres west of H\u0101pua in a native forest remnant.<\/p>\n
Fowler also acknowledged the support of neighbouring landowners, including the Anglican Church Pension Fund, which permitted bat detectors to be placed within a stand of 300-year-old trees that were protected during production forest harvest operations.<\/p>\n
Ultrasonic recorders supplied by The Bat Co. Lab in Havelock North have since confirmed bat activity at H\u0101pua, capturing multiple nightly passes (often in the hundreds), and many echolocation calls – feeding \u201cbuzzes\u201d and social interactions – each night.<\/p>\n

Across Hawke\u2019s Bay, about 70 volunteers assist with detector placement, data collection, and data uploading. <\/p>\n
These volunteers include community groups, high school students, grandparents working alongside grandchildren, schools and local families.<\/p>\n
In addition to H\u0101pua, Roper has recently identified 25 previously unknown sites within a 25 km radius of Te Mata Peak where pekapeka\u2011tou\u2011roa are either roosting or actively using the habitat.<\/p>\n
\u201cThe Bat Co. Lab currently has 107 volunteers nationwide,\u201d Roper said.<\/p>\n
\u201cWe hope that more groups already involved in bush-related conservation projects will join us in placing recorders and gathering data.<\/p>\n
\u201cExpanding volunteer involvement will allow for faster data collection and more accurate habitat mapping.\u201d<\/p>\n
Ecologist and founding director of The Bat Co. Lab, Mark Roper, keeps an eye out for long-tailed bats.<\/p>\n
Fowler reflected on the history of H\u0101pua, noting that there was no record of bats when the previous owner, Jon Williams, grew up on the property in the 1930s and 40s.<\/p>\n
\u201cThese bats are extremely difficult to relocate,\u201d he said. <\/p>\n
\u201cTheir habitat is often destroyed for development or intensive farming. <\/p>\n
\u201cI need to be a voice for the bats.\u201d<\/p>\n
H\u0101pua contains remnants of native bush with a diverse range of indigenous tree species, and Fowler\u2019s vision is to expand this habitat. <\/p>\n
The property already supports species such as the New Zealand falcon, long-finned eel, New Zealand dabchick (weweia), kerer\u016b, t\u016b\u012b, barn owl and fantail.<\/p>\n
\u201cFinding the bats is only the first step,\u201d Fowler said. <\/p>\n
\u201cThe goal now is to ensure that H\u0101pua remains a stronghold for the pekapeka-tou-roa for the next 25 years and well into the future.\u201d<\/p>\n
