This version contains 57,551 meshblocks, including 16 with empty or null geometries (non-digitised meshblocks). Stats NZ maintains an annual meshblock pattern for collecting and producing statistical data. This allows data to be compared over time. A meshblock is the smallest geographic unit for which statistical data is collected and processed by Stats NZ. A meshblock is a defined geographic area, which can vary in size from part of a city block to a large area of rural land. The optimal size for a meshblock is 30–60 dwellings (containing approximately 60–120 residents). Each meshblock borders on another to form a network covering all of New Zealand, including coasts and inlets and extending out to the 200-mile economic zone (EEZ) and is digitised to the 12-mile limit. Meshblocks are added together to build up larger geographic areas such as statistical area 1 (SA1), statistical area 2 (SA2), statistical area 3 (SA3), and urban rural (UR). They are also used to define electoral districts, territorial authorities, and regional councils. Meshblock boundaries generally follow road centrelines, cadastral property boundaries, or topographical features such as rivers. Expanses of water in the form of lakes and inlets are defined separately from land.Meshblock maintenanceMeshblock boundaries are amended by:1. Splitting – subdividing a meshblock into two or more meshblocks. 2. Nudging – shifting a boundary to a more appropriate position. Reasons for meshblock splits and nudges can include:·to maintain meshblock criteria rules. ·to improve the size balance of meshblocks in areas where there has been population growth·to maintain alignment to cadastre and other geographic features.·Stats NZ requests for boundary changes so that statistical geography boundaries can be moved ·external requests for boundary changes so that administrative or electoral boundaries can be moved ·to separate land and water. Mainland, inland water, islands, inlets, and oceanic are defined separatelyMeshblock changes are made throughout the year. A major release is made at 1 January each year with ad hoc releases available to users at other times.While meshblock boundaries are continually under review, 'freezes' on changes to the boundaries are applied periodically. Such 'freezes' are imposed at the time of population censuses and during periods of intense electoral activity, for example, prior and during general and local body elections.Meshblock numbering Meshblocks are not named and have seven-digit codes.When meshblocks are split, each new meshblock is given a new code. The original meshblock codes no longer exist within that version and future versions of the meshblock classification. Meshblock codes do not change when a meshblock boundary is nudged.Meshblocks that existed prior to 2015 and have not changed are numbered from 0000100 to 3210003. Meshblocks created from 2015 onwards are numbered from 4000000.Digitised and non-digitised meshblocksThe digital geographic boundaries are defined and maintained by Stats NZ.Meshblocks cover the land area of New Zealand, the water area to the 12mile limit, the Chatham Islands, Kermadec Islands, sub-Antarctic islands, offshore oil rigs, and Ross Dependency. The following 16 meshblocks are not held in digitised form.<table><tbody><tr><td>Meshblock</td><td>Location (statistical area 2 name)</td></tr><tr><td>0016901</td><td>Oceanic Kermadec Islands</td></tr><tr><td>0016902</td><td>Kermadec Islands</td></tr><tr><td>1588000</td><td>Oceanic Oil Rig Taranaki</td></tr><tr><td>3166401</td><td>Oceanic Campbell Island</td></tr><tr><td>3166402</td><td>Campbell Island</td></tr><tr><td>3166600</td><td>Oceanic Oil Rig Southland</td></tr><tr><td>3166710</td><td>Oceanic Auckland Islands</td></tr><tr><td>3166711</td><td>Auckland Islands</td></tr><tr><td>3195000</td><td>Ross Dependency</td></tr><tr><td>3196001</td><td>New Zealand Economic Zone</td></tr><tr><td>3196002</td><td>Oceanic Bounty Islands</td></tr><tr><td>3196003</td><td>Bounty Islands</td></tr><tr><td>3196004</td><td>Oceanic Snares Islands</td></tr><tr><td>3196005</td><td>Snares Island</td></tr><tr><td>3196006</td><td>Oceanic Antipodes Islands</td></tr><tr><td>3196007</td><td>Antipodes Islands</td></tr></tbody></table>High-definition versionThis high definition (HD) version is the most detailed geometry, suitable for use in GIS for geometric analysis operations and for the computation of areas, centroids and other metrics.

Non-alignment of meshblock and cadastral boundaries are one of a number of reasons for meshblock boundary adjustments. Other reasons include requests from local authorities, Local Government Commission, Electoral Representation Commission and to make census enumeration processes easier. From the generalised meshblock pattern, higher geographies are dissolved using the dissolve tool in the Arc GIS suite to create multiple output datasets. 0 EPSG 6.15(9.0.0) Simple FALSE 0 TRUE FALSE /9j/4AAQSkZJRgABAQEAAQABAAD/2wBDAAgGBgcGBQgHBwcJCQgKDBQNDAsLDBkSEw8UHRofHh0a HBwgJC4nICIsIxwcKDcpLDAxNDQ0Hyc5PTgyPC4zNDL/2wBDAQkJCQwLDBgNDRgyIRwhMjIyMjIy MjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjIyMjL/wAARCACFAMgDASIA AhEBAxEB/8QAHwAAAQUBAQEBAQEAAAAAAAAAAAECAwQFBgcICQoL/8QAtRAAAgEDAwIEAwUFBAQA AAF9AQIDAAQRBRIhMUEGE1FhByJxFDKBkaEII0KxwRVS0fAkM2JyggkKFhcYGRolJicoKSo0NTY3 ODk6Q0RFRkdISUpTVFVWV1hZWmNkZWZnaGlqc3R1dnd4eXqDhIWGh4iJipKTlJWWl5iZmqKjpKWm p6ipqrKztLW2t7i5usLDxMXGx8jJytLT1NXW19jZ2uHi4+Tl5ufo6erx8vP09fb3+Pn6/8QAHwEA AwEBAQEBAQEBAQAAAAAAAAECAwQFBgcICQoL/8QAtREAAgECBAQDBAcFBAQAAQJ3AAECAxEEBSEx BhJBUQdhcRMiMoEIFEKRobHBCSMzUvAVYnLRChYkNOEl8RcYGRomJygpKjU2Nzg5OkNERUZHSElK U1RVVldYWVpjZGVmZ2hpanN0dXZ3eHl6goOEhYaHiImKkpOUlZaXmJmaoqOkpaanqKmqsrO0tba3 uLm6wsPExcbHyMnK0tPU1dbX2Nna4uPk5ebn6Onq8vP09fb3+Pn6/9oADAMBAAIRAxEAPwD3+iii gAooooAKKKKACqF5YSTStcW1y8E5j2ZUAhsEkZyPUn86v0UAVLC6e4jeOeMx3EJCyLnIzjOQfQ1b rNu1+x6hDejd5chEMwB45ICsR7Hj8a0qACiiigAooooAKKq3V/HbOsSq01w/Kwx8sR6+w9zxUROq TH5Vt7ZfViZG/IYH60AX6rz31rbMEmuI0c9FLcn8OtQf2YZWDXN5cTf7IbYv5Lip7extbUfuLeOP 1KryfxoAo6tewSaDdzxP5sUYHmhOSFBG4Y9dua04ZUngjliIaN1DKR3BqtdaXa3bl5FYMww5Riu8 ejY6io9G40/yuhikkjI+jH+mKANCiiigAqC7NstuzXfl+SOvmYx+tT1j2sCf2pJHf/vrncZIHf7p TP8ACOgI4B/PvQBNpCuqzFEdLNmzbrJ94Dvx2X0B5orSooAKKKKACiiigAooooAKKKKAKWrj/iVX B/uKH/Ig/wBKuKdygjuM1n6xzbQo3Eb3EayE9huz+pAH41o0AFFFFABWbf3F59ths7RoY2ljd/Ml UnGCBgD15zWg7rGpZ2CqOpJxWXA0+pX0dyY41soXYwtk73OMZx6cnFAF2zs0tFY7jJM5zJK33mP+ HtVmiigAooooAKoaNg2BPczzZ+vmNV+s+zIt9Su7UnHmEXEY7EHhsfQjJ/3vegDQooooAKrXtoLu IBW2TRnfFIP4W/w9as0UAU9Nvlv7ZnGBJFI0Uqg5CuvUZoqAwz6ddTS2sBmt5jvaJWAKP3Izxg+n rz3ooA06Kom41FBlrCN/aOfJ/UCo/wC0ronaNIuw/wDtNGF/MMaANKoLm9t7TaJpArN91QMs30A5 NVf7SnkwsGm3Jc9TIAiqfck5/IGpbOyMLNPcOJbqT7744A/ur6CgCL7Vf3IP2a0EA7SXR/8AZRz+ ZFKJtUh+WS2guCejxOUH4g5x+BNaFFAGYNYS3laLUlW0kB+Q7iySDA6NgdM8itJWDKGUggjII70j Ro+N6K2OmRnFZlxpEMEBmsI2juIzvTDtg4/hxnoRxigB+ptJdSLpkOwNNGzyOwzsQEDgepJ4+hrQ XCKqFsnGBk8msa11CN0udVEbETOsECkYL44A9vmLD8KtRaVHMjSagqT3En3jjhPZfQD1oAmur7yJ Fghiae4YZEanGB6sewqAaW848y8urhpjziGZo0T2AXGfxzVm0sobJWEe9i33ndizH05NWaAKCaPa Bt8wkuX9bhy4/AHgfgKvABQAAABwAKWigAooooAKKKKACszV22yWbQsRd+aBGAMkoSA/Hpjn8q06 y7qUPrVp9mRpZotyTY+7HGwBOT65VcDrQBqUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAcz4g i+x3Fk8LtDBPcr55zlRg7gQvY5Gc+xrpqqajYpqFm0D4zuV1JGcMpyDj6il025e7sIpZUCycq4HT cCQce2RQBaooooAKzr+zvbi6R7e68mNVGQCck5z06dK0aKAMSfStTdFEWqurDqT9B/gfzrVtI5Yb WOOaTzJFXDP61NRQAUVXmv7SBJGluYkEZCvlhwT0H19qryaoHXbZ289xIen7soo+rNgUAOvrqZZ4 bW0eL7RISxDjO1ADyQPfin6daNZ2uyQq0ru0kjKOCzEn+uPwosLJbOABgrTv80snd27nNW6ACiii gAooooAKKKKACiiigAooooAKKKKACiiigCOeZLeCSaU4jjUsx9AKqaTHIlo7uuwTSNKkf9xTzj+v 407VreS609o4kDuHRthOAwDAkfiAaLPUVuJXt5YWtrhP+WUmPmX1U9xQBdooooAKKKKACobu5Szt XnkyQo4A6sewHuTxU1ZWvq7WdvtTIF1CWbOCg3jkfy/GgB+n6YkbveXMMX2uZzISFH7vIxgH6d+5 zWlRRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFABUNzaW92m2eJX9CRyPoeo/CpqKA M4i8085TfeW3Hyk/vU+n94fr9at211Bdx74JAwBwR0IPoR2NTVSvLHe32m2cQ3SjhwOG9mHcUAXa Kr290s1hHdSYjVow7ZPC8c81WfVo5Ij9jjmnlYfIBEwU++4jGPegDQLBRkkD61kJFLrTJcvNJDZK 6vFEu3Mu1gwZjg8ZA4Hb61Yi0qBv3l4oup2HzNKMgeyg8AVfVVRQqKFUDAAGAKAFooooAKxHm11r qURRRLEGO0yIORuGOjema26KAOfFx4jNyB9mi8ncASVGcdyPm9f0z7V0FFFABRRRQAUUUUAFFFFA BRRRQBk6ppV3fzrJDqMlugTb5ajjPr1qo3h/UWUj+3Jx6AL0+779sfrXQ0UAV7GCS1soYJZjM6Lg yHq1WKKKACiiigAooqrqM8lvZO8RUSkhE3DI3E4H86AMiyt57q/urR8/2XazYj3HmQ4B28dVBJ/L FdD0qtY2gsrbyt5dizO7kY3MxJJ/WrNABRRRQAUUUUAFFFFABRRVOfUYopTDGjzzDrHEMlfqegoA uUVmW17eHUfLu4FhimXMC5ywI6hiOMkc/hWnQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAVna4JD pbiOMs2QdwzmPn74A5OOuK0ao3GqWSI6C4SSXoI42DOT6AUAWoGD28biQSBlB3j+LjrUlZGkXbRW trZXdtLbTrGEUSYIfA7EEjPtWvQAUUUUAFFFFABRRRQBT1SZodPlZHKO2I0YddzEKP1NTW1tFaQi KFAqjr6k+pPc+9NvrUXlq0W7a2QyNjO1lIKn8wKbY3TXMLeYoSaNzHIo6Aj09j1/GgB91apdoquW VkYOjocFT6iqjWV+I3YanK0gHyARoB+PHNVAniAlz5kQXnAO0nv3x9KZbJ4mFxH9pltjFuG/bjpx nt9f0oAtwahqMlvGzaVIHCjeGkVTu74GTxRWrRQAUUUUAFFFFABRRRQAUUUUAFB4GaKKAMPToV1u 2+33pZlkJ2QqzKqKCRg4PzVsRwQwhRHEiBRgBVAxRRQBS1U/NYj1uk5/A1o0UUAFFFFABRRRQAUU UUAFZz5ttaUofluY2Lr/ALSYwfyOPwFFFAGjRRRQAUUUUAf/2Q==
