"Explainer - As the war between Iran and the United States and Israel enters its second month, New Zealand is feeling the pinch at the petrol pump. But what other everyday items could face possible shortages if the conflict escalates?"

This opening frames the article as an 'explainer' on a current, evolving conflict, immediately capturing attention by connecting a global event to the reader's immediate concern (petrol prices) and then raising the specter of 'possible shortages' of other 'everyday items,' creating a Hook-question. This is a common journalistic technique but can serve to hold attention on a particular narrative.

"Much more than just oil may be affected by price rises or even shortages if the Iran war continues to escalate."

This statement broadly suggests a wider, less-anticipated impact beyond the obvious, aiming to intrigue the reader about the 'much more' that will be revealed, thus creating a novelty spike.

"Unexpected shortages such as helium gas could affect MRI machine use."

This highlights a specific, unexpected consequence of the conflict, which is likely to capture attention due to its surprising nature and direct link to critical medical services, making the abstract conflict suddenly very personal and tangible.

"Only 0.6 percent, or $642 million, of New Zealand's total imports are sourced from Middle Eastern countries, the Ministry of Foreign Affairs and Trade notes in its most recent report on supply chains and the Iran conflict."

The article uses an official government ministry (MFAT) report to provide specific data points, lending credibility and an air of factual substantiation to its claims about New Zealand's import dependencies. This uses the institutional weight of MFAT as an authority.

"Dr Sarah Marshall is a senior lecturer at the University of Auckland business school and director of the university's Centre for Supply Chain Management."

The article introduces Dr. Sarah Marshall with her academic credentials and official title at a recognized university, leveraging her presumed expertise in supply chain management to support the article's narrative about vulnerabilities.

"University of Auckland economics professor Robert MacCulloch said if the war carries on, it could potentially be an oil shock on the scale of the 1970s."

Professor MacCulloch's title and affiliation are used to lend significant weight to his warning of a '1970s scale oil shock,' which is a dramatic claim, amplified by his perceived authority in economics.

"Eat New Zealand chief executive Angela Clifford recently told RNZ's Nine to Noon that she would like to see more investment in keep locally produced food on the shelves, rather than imported food."

Angela Clifford, as the chief executive of 'Eat New Zealand,' is presented as an authority on food systems. Her statements about food security and the need for local investment leverage her position to support the idea of vulnerability in food supplies.

"Pharmac said this week it was closely monitoring potential medicine supply risks due to the war."

Pharmac is a government agency responsible for medicine funding and supply in New Zealand. Citing their monitoring of risks uses institutional authority to validate concerns about medical supply disruptions, giving direct governmental backing to the potential issue.

""We can see you can be held to ransom maybe by someone who's very critical in that supply chain.""

This quote from Professor MacCulloch subtly creates an 'us-vs-them' dynamic. 'We' (New Zealanders/consumers) are portrayed as vulnerable and potentially 'held to ransom' by an external, unspecified 'someone' who controls critical supply chains, implicitly linking this to the 'Iran war.'

""We have continued to see the lack of ownership of our food system increase over recent years. You know, we have no security plan, no vision to feed our own people.""

This quote from Angela Clifford weaponizes the idea of national identity ('our food system,' 'feed our own people') to frame the lack of local food security as a failure, implicitly fostering a collective 'us' (New Zealanders) who are being let down, and creating a sense of shared vulnerability that should be addressed by valuing 'feeding our own people first.'

"MacCulloch said successive New Zealand governments of both National and Labour have failed to build supply chain resilience. "They've had 50 years to prepare for this shock, you know, half a century.""

The professor creates an 'us-vs-them' dynamic between 'the people' and 'governments' (both major parties). He positions 'us' (the public) as suffering from failures of 'them' (the successive governments), potentially fostering tribal resentment against political leaders for a lack of preparedness.

"But what other everyday items could face possible shortages if the conflict escalates?"

This question in the lede immediately introduces an element of uncertainty and potential scarcity, designed to evoke anxiety or concern about the availability of essential goods, directly tapping into primal fears of lack.

"We all know about the rising cost of fuel and the immense impact diesel prices will have on the entire country's infrastructure, but there are several other everyday necessities that could be hit by a prolonged war."

This statement amplifies existing anxieties about fuel costs and then introduces the concept of a 'prolonged war' leading to hits on 'several other everyday necessities,' raising the emotional stakes and fostering worry about broad disruptions to daily life beyond the already known.

""I don't think it's overblown to say that potentially the effects are going to be enormous," he said. "In this country it inspired in the '70s the government of Rob Muldoon to change the whole national strategy.""

The use of 'enormous' combined with a historical reference to a significant past crisis (the 1970s oil shock) is intended to evoke substantial fear about the potential severity and transformative impact of the current situation. The reference to 'change the whole national strategy' implies a crisis of unprecedented proportions that requires drastic measures.

"And we should all be careful to avoid the kind of frantic panic-buying that left toilet paper shelves empty during the pandemic, Marshall said. "We saw during Covid that if demand spikes unexpectedly, it can turn a manageable situation into a real shortage. This often gets amplified as that surge in demand moves through the supply chain, so panic buying can make things worse.""

While this offers practical advice, it simultaneously evokes the urgent memory of past panic-buying driven by fear and scarcity during the pandemic, reminding readers of that tense period and indirectly suggesting that similar conditions could re-emerge, creating an emotional undercurrent of potential crisis.

"The Iran war has affected the global supply of a range of raw ingredients, and there were warnings recently that the UK is "weeks away" from possible shortages of everything from painkillers to cancer treatments."

The article uses the vivid example of potential medical shortages in the UK, explicitly stating 'weeks away' from 'painkillers to cancer treatments,' to directly trigger fear and anxiety about access to critical healthcare necessities, linking a distant conflict to very personal, life-threatening concerns.
