The lie of the land in Diamond Harbour
The typical building in Diamond Harbour stands on ground sloping 8.3° (read on an 8 m grid, so short steep banks may be understated), in the steepest quarter of 69 in Christchurch City.
About 14% of its 1,160 measured buildings stand on ground of 15° or more.
The land rises from about 0 m to 553 m, and 40% of all of it, including reserves and gullies, is 15° or steeper.
Unusually much of the sloping land faces north: 38%, where about a quarter would if slopes faced every way equally.
Slope is not a measure of ground stability. Sources and limits

44% of Diamond Harbour's titles are within 200 m of the sea or harbour edge, 96% within 500 m and 100% within 1 km. The typical title is 220 m away.
Measured in a straight line from the centre of each title's land to the coastline on LINZ's 1:50k topographic map, which follows harbours and estuaries as well as the open coast; lakes and rivers are not included.

Source: Christchurch City Council, District Plan open data (CC BY 4.0), layers last edited 2026-09-16. Each title is counted once, at the centre of its land, so a title partly inside an area may be counted outside it and the other way round. These are the council's planning maps for the operative District Plan, not assessments of any property: being outside a mapped area does not mean a site is free of that hazard, and being inside one does not describe any particular site. Zone rules set what can be built; check the District Plan, and the LIM for any property.
Room for a small stand-alone unit in Diamond Harbour
Since 15 January 2026 a new detached unit of up to 70 m² needs no building consent and, in a residential zone, no resource consent, if (among other conditions) it sits at least 2 m from boundaries and other buildings and the site's building coverage stays at or under 50%. Testing those two dimensional rules against LINZ parcel and building outlines for 834 residential sections in Diamond Harbour (250–5,000 m²):
| Result of the public-data screen | All residential sections |
|---|---|
| No obvious barrier: a 7 × 10 m space fits and coverage would stay at or under 50% | 86% |
| … of which also in a mapped hazard, qualifying-matter or noise overlay (check needed) | 100% |
| Space fits but coverage would exceed 50% | 0% |
| No room for the space | 14% |
A screen of two measurements, not advice, and never a statement that anything can be built. Building outlines are approximate and leave out decks, sheds, pools and driveways; easements, land covenants, consent notices, pipes, trees, unmapped hazards and district plan rules that still apply are not visible here. On a cross-lease section the other owners' consent and a new flats plan are normally needed as well, and "one unit per site" may mean one for the whole shared section. The council's Project Information Memorandum (PIM) is the authoritative check.
