Five-yearly census to be scrapped
New Zealand will scrap the traditional nationwide five-yearly census from 2030 in lieu of a system that uses existing government data, smaller annual surveys, and targeted data collection.
Monthly inflation reporting would also begin from 2027 to provide more frequent and up-to-date economic data, Statistics Minister Shane Reti announced today.
He said the new approach will harness administrative data already collected by government agencies as the primary source of population statistics.
This data – including tax records, education enrolments, or health data – is already used regularly to produce some statistics.
A smaller annual survey and targeted data collection will verify the data quality and fill gaps, with Stats NZ to work closely with communities to ensure accurate representation of minorities.

Reti said the approach will save time and money while delivering more timely insights into New Zealand's population, adding that relying on a nationwide census day was "no longer financially viable".

In 2013, the census cost $104 million. A decade later, costs had risen to $325 million, with the next census projected to cost $400 million.
"Despite the unsustainable and escalating costs, successive censuses have been beset with issues or failed to meet expectations," Reti said.
"By leveraging data already collected by government agencies, we can produce key census statistics every year, better informing decisions that affect people's lives."

Reti also said the Government will also spend $16.5 million to introduce a monthly Consumer Price Index (CPI) from 2027, which will measure inflation for New Zealand households by recording changes in the price of goods and service.

The CPI will provide more timely inflation data to help the Government and Reserve Bank respond quickly to cost-of-living pressures and bring the country in line with other advanced economies, he said.
"Inflation affects interest rates, benefit adjustments, and household budgets. Timely data helps ensure Kiwis are better supported in a fast-changing environment."
Stats NZ will also be allocated funding to align its reporting with updated international macroeconomic standards.
"Modern, internationally aligned statistics will support trade and investment, helping drive economic growth and job creation," Reti said, adding that the changes represented a "broader reset" for Stats NZ.
"Some outputs have not met the standard expected of a world-class statistics agency. We're getting back to basics – measuring what matters. Our goal is a modern, efficient, and reliable data system that delivers the insights New Zealand needs now and into the future."
Meanwhile, the Guardian has reported that plans to scrap the 2031 census in England and Wales have been overturned amid a backlash from statisticians over plans to replace it with alternative sources of data.
They were concerned about the feasibility and cost of bringing together different datasets that may have been collected in different ways.

Scrutiny Week Q&A with Green MP Lawrence Xu-Nan
Green MP Lawrence Xu-Nan. Photo: VNP / Phil Smith This week at Parliament is Estimates Scrutiny Week, when government ministers face select committees to defend their budget plans. For an insight into the preparation necessary to properly hold a government to account on their budget estimates, The House chatted with a star performer from last year's scrutiny weeks. Lawrence Xu-Nan is one of a number of MPs in this Parliament who have doctoral-level qualifications. That suggests he holds some brutal research experience that might prove useful in digging into something as labyrinthine and esoteric as the budget. Xu-Nan's background is in Egyptology. If you can translate and analyse ancient fragmentary texts in dead languages, surely the budget is decipherable. "One of the major roles of being an MP and part of the legislature is to scrutinise the Executive. "How they make law is one part of it, and the other part is how they put together their budget and how they're going to spend that budget. So that is what we're going to be seeing this week as one of two scrutiny weeks, [the other being the Annual Reviews in December]. "We will have hearings with both the minister and the ministry or agency, on how they are going to spend the money that they set out in the budget." "I like to take a very methodological approach. "The first thing I always look at is the Summary of Initiatives. So within that, what's new? What has the government introduced that's new? What has the government taken away? That's formed the basis of a number of my questions. "Then you go to the actual Votes. [Note: The sections of a budget are called votes]. Within my portfolio, the two biggest ones are Vote Education and Vote Justice. Getting into the minutia and going through it line-by-line, looking at how the budget is being put together, what money is being spent, what money hasn't been spent." "I've normally put together a massive spreadsheet of all of the different questions. …I then prioritise it, based on the questions I would like to ask, put into different themes. And anything I don't get to ask is put aside as post-hearing questions." "Yeah, I think on one hand I take my role as an MP and as a member of the legislature extremely seriously, particularly around how we hold those checks and balances against the Executive. "And I think …opposition MPs have a particularly important role in that. …Because of my research background, I'm particularly aware that I need to be able to justify the questions I ask and be able to find very quickly where that source is from. So I'll have it with me all the time." "To be fair, in most cases when it comes to select committee, let's say Education and Workforce for example, regardless of which political party you are from, most people are pretty collegial when it comes to asking questions; and the Chair is usually pretty good about allocating the time based on requirement, so often the [Opposition MPs] do get a little bit more time [than their strict proportion]. "I think, if we're looking at maybe roughly 15 minutes or 20 minutes for a really long sustained line of questions [from an initial primary question], within an hour [the hearing] might be able to get four or five main questions [or topics], but everyone has the ability to [ask supplementaries] off each other's questions." Being able to support each other, and bounce off each other, is a really good way of scrutinising the Executive, Lawrence Xu Nan says. Photo: RNZ/ Blessen Tom "It's MP dependent, and it's portfolio dependent. "For example, last year I did a lot of coordination with [Labour MP] Jan Tinetti, as education spokesperson, and I and [the current Labour education Spokesperson] Willow Jean [Prime] have also had conversations around what questions and themes we're going to be looking at this year. "Being able to support each other, and bounce off each other, is also a really good way of scrutinising the Executive, because I think at its core, the intention here is to hold the Executive to account on their budget, as opposed to finding moments where it's less about a "gotcha" moment and more about everyone and the legislature in general working together to scrutinise." "Before the budget is announced, we can put in some pre-hearing questions. And those are a fairly standard list of questions that people may submit. They come from the committee itself to the ministry. So the really important thing about Scrutiny Week (both this week, but also the one in December), is this is one of the few opportunities that we have to be able to not only ask a minister questions (which we can do normally through Written Questions), but to put some questions together to the Ministry. "When the budget is launched, we are then also able to put in some post-budget questions, …on the basis of what is in the budget, and [answers to those] will be available before the hearing; so [you can] prepare more detailed questions based on those responses. "The hearing itself is kind of like [Question Time], and that's when we get to ask some very specific questions, but also, I guess in some ways, the more spicy questions. "After the hearing, depending on whether you have any questions you weren't able to ask, or if new information came about as a result of the public hearing with the minister or with the ministry (or agency), you can put together post-hearing questions. "[Those] can be fairly substantial, and it also allows the ministry time to digest your questions and be able to give you a more fulsome answer." Note - Sometimes questions in a hearing can't be answered immediately and Ministers or officials commit to finding answers for the committee afterwards. "Although I spend a great deal of time and care in putting together my questions… I acknowledge and recognise the fact that not everyone could know every line off by heart - it's just not feasible. "And sometimes you do need to [let people] come back with some of those answers. And we do see that happen quite often during hearings."

Charges filed against KiwiRail over Aratere grounding
Maritime NZ has filed two charges against KiwiRail following an investigation into the grounding of Interislander ferry Aratere last year. The Aratere grounded just north of Picton on June 21 last year, with 47 people onboard at the time. No one was injured and the vessel was refloated two days afterwards, with damage to its bow that required repair. Maritime New Zealand's chief executive Kirstie Hewlett said the charges relate to failures by the operator to keep crew and passengers safe while onboard the ferry, under the Health and Safety at Work Act 2015. "This was a complex incident and important investigation given it focused on KiwiRail bringing in new systems to older vessels and broader safety management. ADVERTISEMENT "It required us to look at systems, policies and procedures, culture, within KiwiRail in relation to the incident." She said a "significant number of interviews were conducted" and a substantial amount of evidence collated. Three investigations are looking at what happened to the vessel when it hit the coastline near Picton. (Source: 1News) "The time taken to undertake this investigation, collate and review the evidence, and decide on compliance action is consistent with other complex and major incidents," she said. "As we have now filed charges in court, we cannot talk about what our investigation found," Hewlett said. In October last year, the Transport Accident Investigation Commission released an initial report into the incident, finding that less than three minutes passed between crew on the Aratere switching on autopilot and the ferry grounding. TAIC will release a final report with further analysis and any possible recommendations at a later date. ADVERTISEMENT Earlier this year, the Government announced the ferry would be retired by August 30 to make way for required Picton port redevelopment in preparation for the two brand-new Cook Strait ferries arriving in 2029. The grounding was just one of many incidents that have plagued the vessel in its 25 years of crossing the Cook Strait. Interislander responds In a statement, Interislander executive general manager Duncan Roy told 1News the company has "made improvements to our processes and systems to avoid an event like this happening again". Roy said an internal investigation carried out in the immediate aftermath of the incident led to nine recommendations – the majority of which have been implemented. "This includes a full review of training processes especially for critical equipment, and reviews of our contractor management and risk management procedures." Since returning to passenger sailings, the Aratere has made more than 1100 crossings of Cook Strait, carrying over 133,000 passengers and 64,000 private and commercial vehicles, Roy said. The vessel's reliability is at 98% this financial year. ADVERTISEMENT In 2024, Interislander brought in independent overseas assessors DNV to review its three ships and their maintenance. Roy said DNV found the ships were in good condition for their age and with the company's stringent maintenance regime, there was no systemic reason why they cannot continue sailing safely until 2029. The charges Charge 1: s48 charge - in that it had a duty as a PCBU, namely to ensure, so far as reasonably practicable, the health and safety of those passengers and crew who would sail aboard the Aratere and that failure exposed crew members and passengers to the risk of death or serious injury. Maximum penalty $1.5m Charge 2: s49 charge under HSWA - in that it had a duty as a PCBU, failed to ensure, so far as is reasonably practicable, the health and safety of those passengers and crew who would sail aboard the Aratere. Maximum penalty: $500,000

Mitchell Contradicted On Lower Police Standards
It's been revealed that Police leadership gave approval for at least two recruits who failed fitness standards to enter Police College. This raises questions about political pressure being applied to the Police College to lower standards. 'Yesterday Mark Mitchell and Richard Chambers emphatically denied any directive to lower standards had been given. However, there are reports that Associate Commissioner Jill Rogers approved at least two recruits who had failed fitness standards to enter Police College,' Labour Police spokesperson Ginny Andersen said. 'This raises serious questions about political pressure being applied to the Police College to fix the Government's failing promise of 500 more police on the beat. 'It also calls into question whether Mark Mitchell was honest with New Zealanders during yesterday's committee hearing. 'He needs to front up and answer whether he was aware that recruits who had failed standards were being allowed to advance. 'When the Government promised 500 more police, the pressure that followed may have contributed to inconsistent and unclear processes. That seriously risks undermining public confidence and the integrity of the Police. 'We need a Police Minister we can trust and who is focused on truly breaking the cycle of crime,' Ginny Andersen said.
