Ah coastal here more or less means directly on it or adjacent. In Auckland you're paying through the nose for that.
Bit colder down here so beachfront property such a big deal. Cheapest suburb that house overlooks you could walk out your door and few hundred meters be at the beach.
The expensive parts woukd be the nice houses on the hill over looking the beach. The really expensive places generally new development at the top of the hill or old Victorian mansion on the hill.
Auckland just double or triple it. Alpine lakes areas also very expensive.
Beach, sportfield, residential. Problem is its reclaimed land with low water table.
Hills in background is where that house is.
