Strategy guide

Shallow-water tiles jump from useless to respectable: +1 Production each, +2 from the Industrial era. In a coastal empire this quietly adds up to dozens of hammers per turn across your cities — often worth more than any wonder. Prioritize suzerainty before your coastal cities mature.

Best civs & plans

A must-fight-for city-state for coastal empires — England, Norway, Indonesia, the Māori and Japan all convert it into a permanent economy boost.

Envoy plan

Treat Auckland as a six-envoy city-state if your empire is genuinely coastal. Suzerainty at three unlocks the tile bonus, but the industrial-type ladder — Production toward districts and buildings in Workshop cities, then in Factory cities — is precisely what a harbour empire lacks, since sea tiles are Food and Gold heavy and hammers are the bottleneck. Expect the AI to fight for it: any coastal civ with Lighthouses values Auckland and the industrial quests are easy to complete. Two envoys above the runner-up is a safe margin. Worth diverting here are the envoys from Diplomatic League's doubled first envoy and from every quest Auckland issues. An inland empire should ignore it completely, however cheap it looks.

Value by era

The bonus is unusual in that it has two distinct peaks. The first comes in the ancient and classical eras, when a coastal city's worked sea tiles go from zero hammers to one and early Harbors, Lighthouses and settlers finish several turns faster; this is when suzerainty is cheapest and the AI has not yet noticed the city-state. The second peak arrives with the Industrial era, when the extra Production doubles and a city working eight or ten coast tiles gains as much as a mid-sized mine cluster. Between those two points the value is steady rather than growing. Late in the game it never fades — coast tiles keep their bonus and seaside cities are typically your largest — so picking Auckland up in the Modern era is still worthwhile if a rival has neglected it.

Pitfalls and how to protect it

The bonus applies to shallow coast, not ocean, so a city on a thin coastline with deep water two tiles out gains little; check how many coast tiles each city can actually work before counting on it. Players also forget that citizens must be assigned to those tiles — the governor's default automation prefers land Food, so lock coast tiles manually in cities where the hammers matter. Do not let Auckland sit undefended on a coast an AI navy can reach; a city-state taken by sea is hard to liberate without your own fleet. If it falls, the improvement is immediate and total, and the smartest reaction is often a naval liberation, because you have the coastal production to build the ships and the liberator regains suzerainty. Levying Auckland's units is a waste unless it needs an emergency garrison.

Envoy bonuses

  • 1 envoy+1 Production toward wonders, buildings and districts in your capital and in each city with a Workshop.
  • 3 envoys+2 Production toward wonders, buildings and districts in each city with a Factory or a Consulate (+4 if the city has both).
  • 6 envoys+3 Production toward wonders, buildings and districts in each city with a Power Plant or a Chancery (+6 if the city has both).

Envoy bonuses are shared by every city-state of the same type.
