ONZKO / PLANNING TOOLS

Measure. Plan. Build with confidence.

Use your measurements and your supplier’s product specifications. Quantities are estimates, not a quote or installation design.

Your space

Example dimensions from a commercial Auckland turf supplier, reviewed September 2026. Confirm your turf variety and current roll size before ordering. This reference is not confirmed ONZKO stock.

Enter your supplier’s specifications or select a commercial reference. Choose your own allowance and optional layer depth. For irregular spaces, calculate separate rectangles without overlaps.

Measure the lawn before ordering

Measure each rectangular section and subtract beds or paving. For an irregular lawn, split it into separate rectangles without counting overlaps. Choose a cutting allowance for the actual shape; the default adds no extra.

Example: 10 m × 6 m is 60 m². With a selected 5% allowance and supplier coverage of 1 m² per roll, order 63 rolls. These are demonstration inputs, not a product recommendation.

What should I confirm?

Check turf variety, roll coverage, delivery access, ground preparation and the supplier’s laying and watering instructions. This tool estimates coverage; it does not select a grass variety for your site.
