Police trial data extraction tech aimed at wearable devices
'The tool can also help classify the data/media found on the device, although this may be limited as [police have] other tools for analysing data during investigations.'
The new capabilities list was the first police had issued in two years.
They have for years used another data extraction tool, Cellebrite — an Israeli technology reportedly used by the FBI to unlock the phone of US President Donald Trump's would-be assassin of last year.
They are also trialling four other new technologies, including two types of artificial intelligence from Microsoft, though only on internal police information and not in any publicly connected way, so far.
One of the two, a cloud-based search tool, 'may improve operational efficiency ... and reduce the likelihood of risks caused by poor information availability and awareness', the new report said.
'Strict keyword searching can lead to important information not being found when needed.'
Controls were in place to 'avoid data leakage to external parties'.
Police have been adding high-tech data-mining tools to try to improve intelligence systems assessments found were disjointed, such as SearchX for frontline officers in 2023.
The Police Commissioner ordered the first such tech stocktake in 2020 only after RNZ exposed they had trialled — without proper authorisation — an algorithm that searches social media for face matches, from US firm Clearview AI. The list was later made public under media pressure.
A fourth technology they were currently trialling stitched drone footage together, and a fifth, under way in central Auckland was of devices that could share text, audio and images on a secure cell network 'to improve response times' in the CBD.
Almost two dozen systems are already in use for investigations. Some, such as BriefCam, which scans CCTV footage, uses facial recognition, but not on live footage, police say.
They recently increased use of automated number plate recognition (ANPR) technology from several hundred to about 2000 times a day, accessing commercial cameras and the software of two private companies to do so.
Court challenges against the use of ANPR in evidence failed last year.

Retailers upbeat following OCR cut
Talk of lower interest rates has retailers feeling more positive about the economy. Photo: RNZ Shopkeepers might have high hopes for an economic turnaround and better sales, but the data indicates otherwise. Retail NZ chief executive Carolyn Young said Wednesday's cut to the official cash rate was unlikely to see shoppers flooding retail stores just yet. The Reserve Bank cut its cash rate by 25 basis points to a three-year low of 3 percent, and left the door open for further reductions. Young said the group's latest quarterly report from April to June,showed 62 percent of retailers did not meet their sales targets. But she said talk of lower interest rates had them feeling more positive about the economy. "Businesses are optimistic that we are through the worst of it, but their trading levels aren't showing that they are. Optimism is based on emotion and trading sales figures are based on fact." She said the next six months would be crucial for businesses facing closure and hoped to see the Reserve Bank deliver on more aggressive cuts. Previous OCR drops had not delivered the hoped-for economic boost, she said. Retail NZ chief executive Carolyn Young. Photo: Supplied "We're not seeing growth, we're not seeing many green shoots, we're seeing businesses that are still being challenged. Businesses closing, laying off staff, doing restructures. We know a lot of retailers are still trading at a loss. "It's a really difficult economic environment. Consumer confidence needs to be higher in order for retail to survive." Young said there was always a lag between rate changes and spending habits, and right now, people were focused on paying for the essentials. Meanwhile, Kelvin Davidson, chief property economist at Cotality, was not expecting any big changes in the housing market following the lowered OCR. He said despite significant falls in the rate over the past year, the housing market had remained flat. "The influence of low mortgage rates is already out there, yet the housing market isn't really responding. "I think what were seeing on the other side of the ledger is restraint from the weak economy and weak labour market, people have lost jobs and even if you've kept the job there's that spillover impact on confidence." Davidson said until there was a shift in the economy and employment rates, the housing market was unlikely to change, and he expected it would remain subdued for the next six to nine months.

Country facing toughest national security environment of recent times: report
By Giles Dexter of RNZ The intelligence service warns threats to national security need to be taken much more seriously than they currently are. The Security Intelligence Service (NZSIS) has released its third annual Security Threat Environment report, containing its assessments of violent extremism, foreign interference, and espionage in New Zealand. The report said New Zealand was facing the most challenging national security environment of recent times, with foreign interference, espionage, and online radicalisation all highlighted as threats. Much of the report contained similar analysis and threats to the two previously released reports, though the NZSIS noted further deterioration since last year's report. This was largely driven by less stable relationships between states, and increasing levels of polarisation and grievance, the agency said. Commenting on the report, director-general of security Andrew Hampton said the deteriorating environment had a direct impact on safety and security. "Increasing levels of polarisation and grievance are driving support for violent extremist ideologies and foreign states are more willing to target New Zealand organisations and communities in order to achieve their aims," he said. "We are seeing active cases of young and vulnerable people being radicalised online, there are foreign states seeking to interfere with our democratic rights, and there is almost certainly undetected espionage activity targeting valuable intellectual property crucial to our future prosperity." Instability The "downward trajectory" of relationships between foreign states becoming less stable and less predictable was continuing. It meant some were wanting to gain more influence, power, and strategic advantage. The relationship between the United States and China was cited, as well as Russia's willingness to assert its influence in Europe. The conflict in the Middle East would also have an enduring impact. The report highlighted the strategic competition in the Indo-Pacific, saying China had demonstrated a "willingness and capability" to undertake intelligence activity targeting New Zealand's national interests, in bids to extend and embed influence across the region. The NZSIS said several states were responsible for foreign interference activities, including transnational repression designed to target diaspora communities. Foreign states had also attempted to exploit people inside the public and private sectors to gain influence. Foreign interference Over the last 18 months, the NZSIS had seen an increase in foreign interference actors visiting New Zealand. The report said these foreign delegations were tasked with building relationships with specific parts of society, often by seeking an invitation from a New Zealand organisation to host them. "On the surface, few organisations will sense any issue but many will not know the delegation's link to foreign interference entities. Members of these delegations will conceal these links so our communities and organisations are unable to assess the risk involved in the engagement," the report said. They have also arranged travel for representatives of New Zealand organisations to build long-term influence. The trips would often include business deals or photo-ops with foreign officials, which were then used by the foreign state to promote a perception of close ties and political support from influential New Zealanders. "This can have an alienating effect on repressed communities back in New Zealand experiencing transnational repression activity from the foreign state." The NZSIS observed diaspora groups were being targeted, with foreign interference groups seeking to co-opt or replace leaders and then sideline anyone deemed to be a challenge to the state's agenda. Certain religions, ethnicities, rainbow communities, and pro-democracy movements were also targeted. While foreign states often flagged legitimate violent extremist concerns with the NZSIS, some states were accusing New Zealand-based groups of being extremists or terrorists when they were not. "The NZSIS is extremely cautious about this deliberate labelling tactic, as it is used to stigmatise particular groups and to justify repressive activity against them." While the report said China was not the only foreign state carrying out activity of concern, it would not specifically name those other foreign states. Online extremism The assessement said the most plausible violent extremist scenario remained a lone actor who had been radicalised online. While no one ideology stood out to the service as presenting a greater threat than any other, grievances and polarising issues online were driving support for those ideologies. Young and more vulnerable people were seen as being particularly at risk of becoming radicalised, with ease of access being a key contributor to the cases brought to NZSIS' attention. "Individuals who hold mixed, unstable or unclear ideologies are especially vulnerable to being radicalised online. The NZSIS has identified a number of people who appear to explore a range of violent extremist beliefs online and adopt certain aspects to suit their grievance," the report said. Violent extremist content was easy to find, and frequently shared in anonymous online networks hosting groups contributing to the radicalisation of people both in New Zealand and around the world. "What might have previously been considered societal risks associated with internet safety, now have the potential to pose an ongoing risk to New Zealand's national security." Artificial intelligence had emerged as a way of facilitating violent extremism and state-sponsored interference activities. "AI is making harmful propaganda appear more authentic and allows it to be spread at scale and speed," the report said. "The ease of access to AI will be assisting violent extremists to research and plan attacks and is reducing barriers that previously made it difficult to access information about more advanced capabilities or weapons." Managing the risks Throughout the report, the NZSIS provided case studies and security advice, with the agency warning it could not automatically pick up on all concerning activities. In mitigating foreign interference, it suggested steps such as researching someone online before agreeing to meet them, or determining whether their interest had become suspicious or persistent. Considering the opportunities and risks of hosting a foreign delegation was also suggested. "We are not all-seeing and all-knowing, and in a democratic society like ours nor should we be. In many cases the public will notice a threat before we do," Hampton said.
