Local context: New Zealand specifics
New Zealand keeps things simple, and Engineering reflects that — one GST rate, metric units, no state-level variation.
Key local facts
- Money: New Zealand dollars, NZ$1,234.56, with GST of 15% baked into consumer prices.
- Tax: Progressive PAYE rates administered by Inland Revenue, deducted at source with no separate annual filing for most employees.
- KiwiSaver: Employee contributions of 3–10% with a minimum employer contribution on top; it sits alongside NZ Super, which is universal at qualifying age.
- Units: Metric throughout — km, kg, litres, °C — and land area often quoted in hectares.
- Power: 230 V / 50 Hz with Type I plugs, and wiring under AS/NZS 3000 shared with Australia.
Local examples
- Example — Auckland: An Auckland household uses Engineering with GST-inclusive figures, since that is how quotes arrive here.
- Example — Christchurch: A builder in Christchurch runs Engineering in square metres, matching council consent documentation.
Every figure above applies to New Zealand specifically and is reviewed when the rules change.
