Buying a farm or lifestyle block
Shortlisting farms: how to read a listing, effective hectares and stock units
Doug Wakelin, Rural/Lifestyle Sales Consultant, Property Brokers Te Awamutu
Short answer. Total hectares is the title size. Effective hectares is the area you can actually farm, after taking out bush, scrub, tracks, buildings and unproductive ground. Stock units measure feed demand: Beef + Lamb NZ counts one stock unit as a 55 kg ewe rearing one lamb, using about 550 kg of dry matter a year.
Terms you'll see on a listing
| Term | What it means | Source |
|---|---|---|
| Total hectares | The area on the title or titles. | Listing |
| Effective hectares | The productive, farmable area. Always ask how it was worked out and by whom. | Industry usage. |
| Stock unit (SU) | A standard measure of feed demand. B+L defines one SU as a 55 kg breeding ewe rearing a lamb, about 550 kg dry matter a year. | Beef + Lamb NZ, as cited in evidence to Otago Regional Council. |
| Winter carrying capacity | The stock the farm winters, for example "850 sheep and 635 cattle". | Listing |
| Contour | Easy, rolling, steep or mixed. Affects stock, fertiliser, tracks and costs. | Listing |
| Farm class | B+L groups farms into classes (for example class 4, North Island hill country) to compare like with like. | Beef + Lamb NZ, farm classes |
B+L publishes current farm survey figures, including typical stocking rates, so ask your agent and farm adviser for up to date numbers.
An example of how to read a listing
Doug's Waitaanga listing says 546.91 ha in total, about 450 ha effective, winter stocking of 850 sheep and 635 cattle, and capable of running at least 80 percent cattle. It also lists a 4-stand woolshed, cattle yards, 30 main paddocks and natural water (PB listing, checked 2 Nov 2026). From that you can start working out feed demand, labour and what the gear can handle.
The shortlist checklist
- Total and effective hectares. Who measured the effective area?
- Contour mix, and how much is easy enough for cattle.
- Winter carrying capacity and what the farm has actually carried.
- Water: troughs, reticulation, source, consent.
- Fencing and paddock numbers. Ask when fences were last renewed.
- Yards, woolshed, shearers' quarters, implement sheds, hay barn.
- Houses: how many, condition, consents.
- Fertiliser and lime history.
- Road access, distance to works, saleyards and services.
- Any trees, ETS registration, covenants or bush blocks.
