The map above is centered on Auckland, New Zealand, near Sky Tower, with a default 15 km radius. Drag to move it, search for a different address, or change the radius and unit using the controls.
Auckland sits between two harbours: the Waitematā (Pacific-facing) and the Manukau (Tasman-facing), and spreads out across extinct volcanic cones and the Hauraki Gulf islands. Distances here are measured from the Sky Tower in central Auckland (-36.848° S, 174.762° E). Distances here are straight-line from Sky Tower — the same way the radius map measures them.
Population figure: Stats NZ, subnational population estimate for Auckland at 30 June 2024.
A 5 km radius drawn from the Sky Tower reaches the central city, the inner suburbs, and Devonport (~3 km northeast) across the Waitematā Harbour. The Waitematā Harbour lies to the east and the Manukau Harbour to the west.
Also known as: Tāmaki Makaurau, City of Sails, Akarana, AKL, The Big Smoke.
Coverage at common radii, including notable places that fall just outside the circle. Use these as a quick reference — check exact boundaries before relying on a circle for real-estate, retail, or service-area decisions.

A 5 km radius from the Sky Tower covers the central city and the inner suburbs, and reaches Devonport (~3 km northeast) across the harbour.
A 10 km radius covers the central city, the inner suburbs, Devonport (~3 km northeast), and the near North Shore (~5 km north); Henderson (~12 km west) sits just outside.
A 15 km radius reaches Devonport (~3 km northeast), the near North Shore (~5 km north), and Henderson (~12 km west); Albany (~16 km north), Howick (~16 km east), and the airport (~17 km south) sit just outside.
A 25 km radius reaches the airport (~17 km south), Manukau (~19 km southeast), Howick (~16 km east), Albany (~16 km north), and Henderson (~12 km west); Waiheke Island (~28 km east) and Papakura (~29 km southeast) fall outside.
A 50 km radius reaches Pukekohe (~41 km south), Orewa (~31 km north), Waiheke Island (~28 km east), and the inner Hauraki Gulf islands, extending well beyond the main urban area.
City-specific scenarios where a radius is the right tool — and a sensible radius to start with.
A 5 km radius from the Sky Tower covers the central city, the inner suburbs, and reaches Devonport (~3 km northeast) across the harbour — a tight circle for searching Auckland's most central rental market.
Suggested starting radius: 5 km for inner Auckland
A 25 km radius reaches the airport (~17 km south), Manukau (~19 km southeast), Albany (~16 km north), and Henderson (~12 km west). The motorway network (SH1, SH16, SH20) is the practical constraint — drive time can vary widely with traffic, especially across the Auckland Harbour Bridge.
Suggested starting radius: 25 km for greater Auckland
Auckland Airport sits ~17 km south of the Sky Tower, in Māngere. A 25 km radius covers the airport plus Manukau (~19 km southeast), Howick (~16 km east), and Henderson (~12 km west) — useful for mapping hotel proximity and ground-transport zones.
Suggested starting radius: 25 km to include AKL
Reaching outer centres such as Pukekohe (~41 km south) and Orewa (~31 km north) takes a wider circle. A 50 km radius reaches those centres but also extends into rural land and the Hauraki Gulf islands.
Suggested starting radius: 50 km for Auckland Region
Local geography and infrastructure that change how a radius behaves here. Skipping these is the most common reason a radius decision goes sideways.
The Waitematā Harbour lies to the east of central Auckland and the Manukau Harbour to the west, with the Hauraki Gulf to the north and east. A radius from the city centre takes in stretches of water on several sides as well as land.
The North Shore is reachable mainly via the Auckland Harbour Bridge (SH1) or by ferry. A 5 km radius 'covers' Devonport (~3 km northeast) geographically, but the road trip wraps around the harbour and can be far slower than the straight-line distance suggests.
Auckland sits on a field of extinct volcanic cones (Mount Eden, One Tree Hill, Rangitoto, and others) — most are parks or reserves with no built population. A radius drawn from the centre passes through several cones, so apparent 'uninhabited' patches inside the circle are usually parks or volcanic reserves, not undeveloped land.
A 15 km radius from the Sky Tower reaches the central city, the near North Shore, Devonport (~3 km northeast), and Henderson (~12 km west). Albany (~16 km north), Howick (~16 km east), and the airport (~17 km south) sit just outside.
A 25 km radius reaches Auckland Airport (~17 km south), Manukau (~19 km southeast), Howick (~16 km east), Albany (~16 km north), and Henderson (~12 km west). Waiheke Island (~28 km east), Papakura (~29 km southeast), and Orewa (~31 km north) are outside.
Yes. AKL sits about 18 km south of the Sky Tower in Māngere, comfortably inside a 25 km radius. A 15 km radius does not quite reach the airport.
Hamilton sits about 114 km southeast of Auckland — well outside a 50 km radius. It is reached on SH1.
Because Auckland sits between two harbours, with the Hauraki Gulf to the north and east and the Manukau Harbour to the west. A large share of the area inside any radius is water — harbour, gulf, or the volcanic cones and parkland that characterise Auckland — rather than inhabited land.
Use a 10–15 km radius to cover the near North Shore (~5 km north) and reach toward Albany (~16 km north), then validate with the Drive Time Map — the Auckland Harbour Bridge is the main northern crossing, so drive time across the harbour can be much longer than the straight-line distance.
