Key concepts

  • Name the standing relationship first

    92030 assesses understanding of how entities with interdependent financial relationships are affected by an event. The official Achieved climb, in EN1, is two jobs: describe a **range** of interdependent financial relationships between entities; describe a direct effect of an event on an entity involved in one of those relationships. Merit then asks for flow-on effects and the impact of each flow-on on a relationship. Excellence asks you to justify a decision an entity could make, and to discuss consequences of that decision for the entities. If the starting object is thin — one side only, no named flow, “they work together,” the word **money** standing alone — later pages have nothing honest to hit with an event. The 2024 and 2025 Assessment Reports have already refused those thin sentences. The 2026 paper is one unseen New Zealand case. It names **four or five** participants. You describe a **minimum of three** two-way relationships, then later how an event moves them. This page only teaches the standing relationship. It will not invent a slip on the rural road. It will not cut Eastline’s hours. It will not ask the government to write a hiring subsidy. It will not draw a circular-flow diagram.

  • The official object is a two-way relationship, not a vibe

    Explanatory Note 2 is the definition you have to earn. Interdependent financial relationships are **real flows and money flows between entities that are financially reliant on each other**. - There are **two entities**. A person thinking about their own pay is not yet a relationship. - They are **financially reliant**. Each needs the other in a way that shows up as a flow you can name. Being neighbours is not enough. Being “in the same town” is not enough. - Something **real** travels. Something named as a **money flow** travels. One sentence that only lists feelings has not yet described the relationship. **Both directions** must be described. That requirement does not come from the wording of EN2. It comes from the Subject Learning Outcomes (“mutually dependent”), from Big Idea 3 (“financial impacts do not travel one way”), and from the reports, which do not reward one side only. The official command you will meet later is ordinary: **Describe the financial interdependence between A and B.** A later Achieved part will then ask for a direct effect of an event. This page only trains the first command. A entity on this standard is any participant the case names. The 2026 specifications say “participants in society.” Official papers also say businesses, households, the Government, a local bank, a non-profit, other local businesses. Use the name the resource gives you. Do not rename Kahu Joinery as “the firm sector.”

  • A real flow is a good, a service or labour

    A real flow is something useful moving from one entity to another that is **not** itself the payment. Official Commerce documents do not print a longer glossary line than EN2’s “real flows.” The sense this page uses is the ordinary Level 1 one: - **Goods** — timber arriving at Kahu; a finished kitchen arriving on a building site; flour arriving at Southwind; a pie leaving the cabinet. - **Services** — Eastline’s delivery run; a bank account the firm can use; a hospital visit; a place at school; a weekday lunch at a community kitchen. - **Labour** — the Moana adult’s driving hours; the apprentice’s hours at the bench; Whaea Tama’s supermarket shift. If you cannot point to a good, a service or someone’s work, you have not yet named the real flow. “Support,” “help” and “a relationship” are not real flows. A real flow has a direction. Timber moves **from** Eastline **to** Kahu. Labour moves **from** the household **to** the firm. A school place is a service moving **from** government **to** the household. Write the direction. Do not draw an arrow. Write it.

  • A money flow is a named payment, not the word “money”

    A money flow is the official EN2 pair of the real flow. It is the payment, wage, tax, interest, transfer or grant that travels the other way. The 2024 and 2025 Assessment Reports are blunt about the word **money**. They will not reward it as a substitute for profit, revenue, income, wages, interest, GST or tax. That is not a style note. It is a marking rule this page has to build as a habit. So the official term is **money flow**. The sentence you write must then **name** the flow: “Kahu gives Eastline money” is the sentence the reports have already refused. “Kahu pays Eastline a $2,400 weekly freight payment, which is Eastline’s revenue” is a money flow. Constructed figures on this page are teaching numbers, not official statistics. Use them to keep the flow named. Do not turn them into a 92031 income statement.

  • Both directions, or it is not interdependent

    Interdependence is **mutual**. The SLO says so in those words. One-way reliance is a customer, a taxpayer, or a worker. It is not yet the official object. The shape later papers accept, and the shape the 2025 sample evidence used, is two clauses: - **A relies on B** for [real flow] so that A can [sell / produce / earn revenue / keep operating]. - **B relies on A** for [named money flow / custom] so that B can [earn revenue / pay wages / keep operating]. Kahu relies on Eastline to transport timber so it can make kitchens and earn sales revenue. Eastline relies on Kahu’s regular custom so it can earn freight revenue. That is one relationship. It is not two. The Moana household relies on Eastline for a wage so it can pay rent and buy groceries. Eastline relies on that adult’s labour so it can complete the Tuesday run and earn freight revenue. That is a second relationship. A **range** of relationships, in EN1 and in the 2026 specifications, means more than one. The live specification asks for a **minimum of three**. Learn three as the exam habit. This page will not yet ask how an event affects those three.

  • Households, firms and government are the three everyday participants

    Topic 1 already named three everyday decision-makers. This page keeps that three-part picture and puts flows on it. A household is the people who share living costs and make a personal or family budget. They supply labour. They receive wages or other income. They spend, which is a firm’s revenue. They pay income tax and GST. They use essential services. Official 92030 papers also say whānau for this participant. Big Idea 3 uses that word. On this page a constructed household is a **92030 participant**. It is still a weak default 92028 organisation — Topic 1 and the 2025 National Moderator’s Report already said so. Do not promote the Moana household into an internal just because it now has two-way flows. A firm in this course is a business: a joinery, a freight company, a bakery, a supermarket, a bank branch as a business. Official papers more often say **business** than “firm.” Treat the two as the same kind of actor unless a resource names a specific organisation. Firms produce goods or services, pay wages, buy inputs, earn revenue, and pay tax. government in Level 1 Commerce is the Crown and local government as financial actors, not a civics essay. The two-way relationship official schedules accept is ordinary and specific: - Households and firms pay **income tax** and/or **GST**. - Government provides **transfer payments** and **essential services** such as **schools and hospitals**. Markers have already refused a list of civic myths. Government does not “provide power and electricity.” It does not “receive tariffs from export sales” or “receive the revenue from export sales.” It cannot “increase tax rates at short notice” as a convenient plot device. Do not invent a fourth flow to make the government sound more powerful. Use the flows the course actually marks. Local government can appear as rates and as a local service — a Saturday bus, a resealed road — when the resource puts it there. That is still government as a financial actor. It is not a licence to turn the council into a power company. Whānau is an official 92030 participant name and the opening word of Big Idea 3. Hapū and iwi appear on the 2026 participant list. This page names the official list. It does not construct a hapū, invent a marae process, or write a “Māori circular flow.” If a later kaiako-approved case actually names hapū or iwi among the participants, use only what that case gives. Do not invent tikanga.

  • The rest of the official cast: community organisations and financial institutions

    The 2026 specifications list more than the three everyday actors. Learn the rest of the list so a case study cannot surprise you by being “not a business.” A community organisation is a club, charity, school or other group with a particular purpose that is not “make a profit.” Topic 1 already taught that profit is not assumed. On 92030 the community organisation is a **participant**. Manawatū Community Kitchen, constructed on this page, exists so people who would otherwise go without have a weekday lunch. A government grant can be a named money flow. The Kitchen receives $48,000 so it can buy food and keep serving. That sentence names the payment. It does **not** make government financially reliant on this one kitchen. Policy hopes and service delivery are not the marked two-way government pair. For a two-way government relationship, use the pair the schedules actually accept: income tax and/or GST one way; transfer payments and essential services the other. The Kitchen still has real two-way relationships. It buys bread from a bakery: bread is the real flow; the Kitchen’s food spend is the bakery’s revenue. That pair has both directions and two named flows. A financial institution on this paper is almost always a **local bank**. Name the interest flows separately. Do not flatten them into one “never reverse interest” rule. **Loan interest** travels **firm → bank**. Kahu relies on Riverbank for a loan and an account so it can buy equipment or hold sales revenue. Riverbank relies on Kahu to pay interest on that loan. Official sample evidence names this pair: loans, accounts, interest **paid by the firm**. **Deposit interest**, when it is paid, travels **bank → household** (or firm). The Moana household may hold a small deposit. The bank may pay a small amount of deposit interest. A sentence that says the bank pays the household deposit interest is not reversed. It is a different flow from loan interest. **How the bank earns from deposits** is a third fact, not a third name for the same payment. The bank can use deposited funds as part of its lending business. That is how the bank earns from deposits. It is not the household’s deposit-interest payment travelling the other way. Banks do **not** collect tax. Banks do **not** pay the firm’s wages. Do not write “the bank gives them money.” Other businesses can appear as a group, the way official papers already have. Builders who buy Kahu’s kitchens rely on Kahu for joinery so they can finish a house and earn their own revenue; Kahu relies on those builders’ custom so it can earn sales revenue. That is still two directions and two named flows.

  • A 92030 participant is not a 92028 stakeholder

    Topic 1 and the stakeholders unit already built three boxes. Hold them. - A stakeholder is someone the organisation would listen to when it chooses (92028). The 2025 National Moderator’s Report does **not** treat suppliers as stakeholders. - An external factor is something outside that can change costs, sales or profit (92029). Official examples include customers **and suppliers**. - A 92030 participant is an entity in a two-way financial relationship. Eastline can be a 92030 participant without becoming a 92028 stakeholder whose *perspective* you examine on a van decision. A flour mill can be a 92030 entity — Southwind relies on the mill’s flour; the mill relies on Southwind’s custom — without becoming a stakeholder on Southwind’s oven paper. A supplier-price rise can later be a 92029 factor. A six-month delay in supplies can later be a 92031 viability factor. Those are different official objects. This page only asks you to write the two-way flows.

  • Name the pūtake of an organisation in the network, then write the flows

    Name the pūtake before the numbers when an organisation is in view. 92030 does **not** make pūtake a grade gate the way 92028 and 92031 do. You will not be asked, on this standard, to discuss impact on pūtake. You still need the reason for being so the flows have somewhere to sit. Kahu Joinery’s pūtake, on these constructed facts, is to make affordable kitchen joinery for local households and to keep apprentices in the city. That is why the Eastline timber run matters: without timber there are no kitchens, no sales revenue, and no apprentice hours. Manawatū Community Kitchen’s pūtake is a weekday lunch for people who would otherwise go without. That is why the grant is not “free money.” It is the named money flow that lets the pūtake become a real service.

  • Write the circular flow. Do not draw it

    Older Level 1 Economics taught a labelled circular-flow diagram: households, firms, government, sometimes a financial sector, arrows for goods and for payments. 92030 papers do **not** ask you to draw that diagram. The idea still has to live in words, because it is the same idea as Big Idea 3. Households supply labour to businesses. Businesses pay wages. Households spend those wages on goods and services. Businesses receive that spending as revenue and supply the goods and services. Households and businesses pay income tax and GST. Government uses that tax take to provide transfer payments and essential services such as schools and hospitals. Some of the wage is deposited at a bank. The bank may lend to a business; the business pays loan interest; the bank earns that interest. The bank may also pay a small amount of deposit interest to the household. A community organisation may receive a grant and turn it into a real service. That is the standing network. Every exam case is a local, named version of those sentences. Write the local version. Do not sketch the arrows. Do not spend a paragraph on “the circular flow of income” as if the diagram were the answer. The answer is Kahu and Eastline, or Southwind and the Tama household, or the Moana household and the government, each with both directions named.

  • Money flows and real flows

    On a Tuesday in Palmerston North a truck backs up to a joinery workshop. The driver is dropping kiln-dried rimu for next week’s kitchens. Kahu Joinery cannot finish a bench without that timber. Eastline Freight cannot pay its driver, or its own diesel, if Kahu stops booking the run. Nothing dramatic has happened. No storm, no new tax, no closed customer. Two organisations are already financially reliant on each other. Something real is moving one way — timber, and the labour that carries it. Something named is moving the other way — a freight payment that is Eastline’s revenue and Kahu’s expense. That two-way picture is the starting object of this page.

  • Events and direct effects

    On a Tuesday in Palmerston North the standing picture is already there. Kahu Joinery still needs kiln-dried rimu. Eastline Freight still needs Kahu’s weekly custom. The Moana household still supplies a driver and an apprentice. Riverbank still holds Kahu’s loan. Manawatū Community Kitchen still turns a government grant into a weekday lunch. Those pairs were named on the last page: a real flow one way, a named money flow the other, each entity relying on the other. Nothing on that page had to break for the relationships to exist.

  • Flow-on effects and relationships

    The Tuesday timber run is already named. Kahu Joinery still cannot finish a bench without Eastline’s truck. Eastline still cannot earn the $2,400 weekly freight payment without Kahu’s custom. The Moana household still supplies the driver’s labour and still takes home a wage. Riverbank still holds the loan and the small deposit. Manawatū Community Kitchen still turns a government grant into a weekday lunch. Those standing pairs were the first Topic 4 page. They have not gone away.

  • Decisions in a financial network

    The standing picture in Palmerston North has not gone away. Kahu Joinery still exists to make affordable kitchen joinery for local households and to keep apprentices in the city. Eastline Freight still needs Kahu’s weekly custom. The Moana household still supplies a driver and an apprentice. Riverbank still holds the loan and the small deposit. Manawatū Community Kitchen still turns a government grant into a weekday lunch. Those pairs were the first Topic 4 page. A slip has already closed the rural road Eastline uses. Eastline’s freight revenue has already decreased. The driver’s hours have already fallen, so household wage income has decreased, deposits at Riverbank have decreased, and tax and GST take have decreased. Those sentences belong to the last two pages. This page does not rewrite them.
