Yes, wonders. Plural. Because there’s attractions abound on this North Island tour. The first: the Bay of Islands, a gem-like archipelago of 144 drops of land. The second: steamy Rotorua, with its geothermal hot springs and spas. The roll-call continues: glow-worm caves, immense waterfalls, mirror lakes and the opportunity to delve into Maori culture over a hangi meal.
