How New Zealand actually works
Short explainers on the systems that shape daily life here, the voting system, the Treaty, the tax code, the health system, the rest, written for someone in Christchurch who is curious but has never read a policy document.
Every page answers the same questions: what it is, how it came to be, who decides, what it costs, where the arguments are, and where to read the primary source. Every number carries its source and its date. Where the parties disagree, each position gets one line and none is ranked. Where a system has a Christchurch face, the page says so.
- MMP, how the voting works The party vote and the electorate vote, the 5% threshold, the seat that unlocks the rest, how coalitions form afterwards, and the review whose recommendations were never adopted.
- Te Tiriti o Waitangi, the two texts The three articles in English and Māori side by side, why they differ, the Waitangi Tribunal, what a settlement is, and the Ngāi Tahu settlement that covers this ground.
- Tax, what is taxed and what isn't The income brackets, GST, company and trust rates, the things New Zealand chooses not to tax, and the IRD study that measured what the wealthiest families actually pay. The long read, the system, the evidence, and the 2026 argument →
- Housing, why it costs what it does Why prices rose, what zoning and the RMA had to do with it, the Auckland upzoning evidence, post-quake Christchurch rents, enrolment zones, and how your rates split land from buildings.
- Welfare, the benefit system The main benefits, who qualifies, the income thresholds where help is clawed back, the obligations that come with it, and where the parties differ.
- NZ Super, the pension everyone gets Who gets it, how much, what it costs the country, where the cost is heading, and why no party ever changes it.
- Health, what the public system covers How Health NZ is structured, what is free and what isn't, what a GP visit costs, how long the waits are, and how the funding compares overseas.
- Education, schools and how they're funded Deciles and the Equity Index, enrolment zones, NCEA, the structured literacy change, and what the international tests say.
- Surveillance and intelligence The GCSB and the SIS, Five Eyes, the Waihopai station, what the 2013 and 2017 laws changed, the post-2019 counter-terror changes, and who watches the watchers.
- Local government, who does what What Christchurch City Council controls and what Environment Canterbury controls, how your rates are set, why Hagley Park is legally protected, and how to make a submission.
- Law and rights, the rules that bind and the ones that protect Where the rules come from, the rights you carry and the ones you use most, your 20-working-day right to ask the council anything, and the Christchurch layer: bylaws, the District Plan, and the yellow stickers.
- The economy in one page What the country sells to the world, the housing-to-productivity link, how big government spending is against other countries, and the debt number.
- Immigration, who gets in and on what terms The visa categories, the points system, partnership visas, the wait before benefits, and where net migration is heading.
- The OIA, how to ask the government for its own records The Official Information Act and its council twin LGOIMA, who can ask, the 20-working-day clock, the refusal grounds, the charges, the Ombudsman, and the open-meetings half.
- The RMA, how New Zealand decides what gets built where The rulebook behind every consent on the feed, the six activity statuses, the notification lanes, the clocks, the submission rights, and the two replacement acts passed in September 2026.
- Renting, the rules between landlord and tenant The bond cap, the 12-month rent rule, healthy homes, the notice clocks both directions, pets since December 2025, and the Tenancy Tribunal behind it all.
- Voting, how New Zealand actually elects people Enrolment, the two election systems, postal-only local elections, FPP versus STV, what the Christchurch ballot elects, the 2025 result, and the referendum this city didn't hold.
- Civil defence, who is in charge when it goes wrong NEMA and the CDEM groups, who can declare a state of emergency and what it unlocks, the phone alert and the sirens, and the city's red-orange-yellow tsunami zones.
- ACC, the deal that swapped lawsuits for cover No-fault injury cover for everyone in the country, what it pays, the five levy accounts that fund it, the accident-versus-illness line, and the right to sue it replaced.
- Privacy, your information and the rules around it The thirteen IPPs and the new IPP 3A, your right to see and correct what agencies hold, mandatory breach notification, and the Commissioner behind it all.
- Courts, where disputes actually get decided The Disputes Tribunal to $60k, the District Court to $350k, the High Court above, the tribunal swarm alongside, and the city's Justice Precinct on Durham Street.
- Disputes, where small fights get settled The Disputes Tribunal to $60,000 with no lawyers, the Tenancy Tribunal's $29 filing, the ERA for work fights, and what an order is actually worth once you win.
- Family law, the kids, the property, and the exit Guardianship versus day-to-day care, the three-year equal-sharing rule, contracting out, the two-year dissolution and its new protection-order exception, and Police Safety Orders.
- Wills and estates, what happens to your stuff What a will does, the fixed intestacy formula, the $40,000 probate threshold, enduring powers of attorney, and who can override the will.
- Public transport, who runs the buses and what a ride costs ECAN plans it, private operators drive it, the city council builds the stops, the July 2025 fares, the caps and concessions, the Diamond Harbour ferry and Total Mobility.
- Driving, licences, demerits, and the drink-drive numbers The three-stage licence ladder, the demerit schedule and the 100-point cliff, the real alcohol limits by age, and who writes the parking tickets in Christchurch.
- Work, the floor under every job, and what happens when it goes wrong The written agreement, the $23.95 floor, leave, breaks and KiwiSaver, then the 90-day trial, the 90-day grievance clock, free mediation, and the gap where redundancy pay isn't.
- Consumer rights, what the shop owes you and what the sign can't take The CGA's guarantee that the thing must work, the remedy ladder, the FTA's no-lying rules, and the five-day cooling-off on a sale that came to your door.
The Christchurch shelf
The same treatment, pointed at the city's own machinery, the rules, the risks and the record a Christchurch reader actually meets.
- Rates, what the bill buys How the council prices a property, what the lines on the invoice fund, and where the money actually goes.
- District Plan, what the rules say your land can do Zones, overlays and the rule inputs a consent reads, the document that decides what can stand where.
- Consents, what needs permission and who decides Resource versus building consent, notified or not, and the hearing that decides a contested one.
- Community boards, the layer under the council What a board can and cannot decide, who sits on one, and why the local issues land there first.
- Water, the aquifers under the city Why Christchurch water needs no treatment, where it comes from, and what the stormwater system does with a flood.
- The earthquakes, the sequence that remade Christchurch The unmapped fault that opened in September 2010, the shallower February rupture that killed 185 people, and the aftershock years still arriving.
- Flooding, the maps that decide who worries River, drainage and tidal floods, the quake-dropped east, the flood floor rules, and how to check an address.
- Liquefaction, the ground that remembered it was swamp Why the east failed in the shakes, the drained wetland under the suburbs, what the surveys mapped, lateral spread, and the zones that followed.
- The rebuild, the machinery that zoned the fallen city Red zones and technical categories, who decided, and what the anchor projects did to the centre.
- Heritage, what gets protected and who decides The district-plan schedule, the Heritage NZ list, what a listing actually forbids, and what survives of the old city.
- Checking a house, the LIM, the records, the red flags The certified property file, what the quake claims record tells a buyer, and the checks worth doing before the offer.
- Reporting, getting the council to fix something Snap Send Solve and the service-request system, what each kind of report triggers, and what the record shows.
- Crash record, the map of where people get hurt NZTA's crash archive by suburb and intersection, what the severity grades mean, and the corners that keep appearing.
- The buses, who runs them and how the network is shaped ECan's Metro brand, the radial network and its two exceptions, and where to plan a trip from.
The method
Every number on these pages names its source and its date next to it, Stats NZ, the Treasury, IRD, MSD, the Ministry of Education, the Electoral Commission, legislation.govt.nz, the Waitangi Tribunal, or the council itself. Where a topic is contested, the page states each party's position in one line and does not pick between them. Where the official number and the lived reality diverge, an abatement rate, a wait list, the page says both. Each page carries the date it was last checked; systems change, and a stale number is worse than no number.
These pages explain the systems; they do not argue for or against them. Corrections go through the same door as everything else on the site, /corrections.
