What You Need To Know If Your CV Is Less Than You Owe On Your Property
Article – RNZ Many Auckland property owners have seen the capital value, or CV, of their properties drop in the past week. Valuations have been updated for the first time since 2021, when New Zealand's property market was hitting post-Covid heights. The new CVs are dated to mid-last year, and typically dropped 9 percent, on average. For some buyers, particularly those who purchased recently, that's been uncomfortable reading. But mortgage advisers say, in general, the CV of a property doesn't matter a lot to lenders. While a drop in value would decrease an owner's equity in a property on paper, they say lenders rely on other methods to determine a property's value and the owner's stake in it. 'It's yesterday's news,' said David Cunningham, chief executive of Squirrel. He said while people might look at a property's CV because it was public information, it was no longer used in calculations for a mortgage. 'In the old days it was but you know now you've got all these models from Cotality and Valocity and so on – and you can go on to or One Roof and find a pretty damn good valuation. They've got the benefit of being pretty much real time.' He said people did not need to worry even if their CV showed they now owed more than their home was worth. He said banks talked about home loan customers being 'delinquency managed' which meant that it was only if they stopped paying their home loans that the bank would investigate. Borrowers who were facing trouble with repayments should talk to the bank before that happened, he said. Some borrowers are paying low-equity premiums because they took out loans with less than 20 percent deposit. These margins can be removed once the loan is paid down, or the value of the property increases to the point where the owner has 20 percent equity. But Cunningham said the new CVs would not affect that process either. People who had built up enough equity to have the margin removed would typically be using banks' desktop valuation data to do so. 'Registered valuations might come into play if it's an unusual property or in an area where there aren't a lot of property sales. So some of the more provincial locations and properties … but for major centres the valuation models, called AVMs, automated valuation models, are what the bank uses.' Glen McLeod, head of Link Advisory, agreed banks would usually use desktop valuations to get an idea of the value of a property, or a registered valuation in situations where it was necessary to be precise about a value. 'If you have a sale and purchase agreement for $850,000 and the registered valuation comes in at $850,000 that's what it's worth even if the CV is $750,000.' Loan Market mortgage adviser Karen Tatterson agreed CVs were rarely used by banks to assess loan-to-value ratios, if ever. She said the problem was that CVs were quickly out of date. 'The Auckland Council CVs that were released yesterday are based on a value ascertained approximately a year ago so they are already out of date and do no reflect the true 'market' value of the home.'

A Bold Dream Gets A Cut As Predator Free 2050 Ltd Is Disestablished
Article – RNZ Predator Free 2050 was hit by a budget blow, and now the 'moonshot' goal is under threat, for The Detail The environmental sector worries that the future of a predator-free Aotearoa is in jeopardy after the Government swung the axe in the latest budget. It was billed as a 'moonshot' for New Zealand's environment – a bold, world-leading goal launched by Sir John Key in 2016, aimed at eradicating rats, possums and stoats from our islands by 2050. The vision has been clear – bring back birdsong to every valley, protect the flightless kiwi, and restore what once thrived. But today, the future of Predator Free 2050 looks uncertain. Predator Free 2050 Ltd, the Crown-owned company established to drive and fund large-scale eradication and breakthrough science, is now being disestablished, as announced as part of Budget 2025. Funding for the company will cease by the end of the year, with its responsibilities shifted to the Department of Conservation (DOC), which the government says will reduce duplication, increase efficiency and save about $12 million. 'People are now worried for this programme,' Newsroom environment editor David Williams tells The Detail. 'They say without ongoing funding, we will not only not go forward, but we will go backwards. This programme needs funding, and that's up to the government.' The government insists the broader goal of predator eradication remains. But Dr Kayla Kingdon-Bebb, chief executive of WWF New Zealand, is not entirely convinced. 'New Zealanders believe in the Predator Free 2050 dream, and we want the government to get behind them too. But I'm not sure this will happen. 'I've not been seeing a lot of enthusiasm for environmental outcomes from this government, full stop. We describe the government's policy agenda as a war on nature, and I think it is disappointing that a previous National government got so strongly behind this moonshot objective, and this government does not seem to care so much.' Both Williams and Kingdon-Bebb say the country has 'overwhelmingly' backed the Predator Free 2050 initiative, allowing it to 'come a long way, in a relatively short time'. Already, predator-elimination projects cover more than 800,000 hectares. 'This is a big amount of land,' says Williams. 'And the goal is big … but they have done well. 'They also said they wanted to fund scientific research, and 15 or 20 projects have already had money to try and sort this problem out. 'A lot of community groups have latched on to this – someone said to me that this is the one conservation project that has captured the imagination of New Zealanders more than any other.' Kingdon-Bebb agrees. 'It has certainly captured the hearts and minds like nothing else,' she says. 'We have seen an explosion of community trapping groups and landscape-scale projects over the last nine years, which has been amazing … now I feel the government is taking its foot off the pedal. 'What is apparent is that the government has had a look at the delivery model of the programme as a whole, which is complex. 'So, if it is the case that the government has reviewed it and determined that a crown-owned corporation is not the best delivery methodology, I can accept that. 'DOC has a lot of capability … and perhaps it is appropriate for DOC to be coordinating this work, perhaps there was duplication of roles and functions and costs. 'But where I would be concerned is that in the wider scale of what has happened in the last two budgets, the Department of Conservation will see, in total, about 300 million dollars in savings exacted from it. 'So, it does beg the question whether a very stretched department can pick up the leadership of this initiative in a way we would want to see it done.' Critics say that move will slow momentum, bury innovation under bureaucracy and confuse local projects already stretched thin. They also argue that across the country, hundreds of predator-free community groups, many driven by volunteers, will be left wondering what support will look like without the company's funding, research backing and strategic oversight. But the government insists the predator-free projects and contracts funded by the company are not affected and it is committed to the predator-free 2050 goal.

Collins coy over possible Aukus pact review
Defence Minister Judith Collins. Photo: RNZ The Defence Minister says there's no reason for New Zealand to comment on reports the Pentagon is reviewing the Aukus defence alliance. A US defence official told Reuters the review was part of ensuring the security pact was aligned with US President Donald Trump's America First agenda. The strategic pact between the US, UK and Australia had long been a talking point in New Zealand, with consecutive governments pondering whether to join parts of the alliance. Aukus was formed in 2021 to address shared worries about China's growing power. Under the pact, Australia would be armed with nuclear submarines at a cost of $A350 billion ($NZ377 billion). In a statement, Defence Minister Judith Collins said the US review was about Aukus Pillar One, which New Zealand had never been a part of. New Zealand has had ongoing discussions about joining Pillar Two of the alliance, but any decisions on whether to join Pillar Two would be a matter for Cabinet, Collins said. Prime Minister Christopher Luxon has not received any reports or advice on what the Trump administration reviewing the Aukus security pact might mean for New Zealand. Luxon told RNZ he was not concerned the review could spell the end for Pillar Two "It's been left very open-ended. We're exploring Pillar Two - it's been to be honest quite slow going. "We are yet to be invited to partipate in Pillar Two." Luxon said the review was for Australia, the US, and the UK to work through. Australia was last week told by US Defense Secretary Pete Hegseth to significantly boost its defence spending. Australian Prime Minister Anthony Albanese said he would not be dictated to on defence spending. He he noted Australia's defence spending was already set to increase from 2 percent to 2.3 percent of Gross Domestic Product (GDP) over the next eight years. Collins has denied any allies have put pressure on the government to up defence spending. Foreign Minister Winston Peters previously said New Zealand's trading partners would judge us if we did not "step up" and play our role by increasing defence spending.
