Can a coprosma survive without water?

Java

Yes, coprosma needs water in order to live.

Specifically, the plant in question can be ground growing natively on Australia, Borneo, Hawaii, Java, Juan Fernández Islands, New Guinea and New Zealand. It is used to moisture in the air and in the soil. But it will not like supplemental irrigation any more frequently than every 10 days unless the area in which it is growing is experiencing such environmental stress as extreme drought.
