My mom and I are planning our first trip to Australia/New Zealand in Mar 2013. We'll be doing a cruise from Sydney and winding up in Auckland, where we are spending 4-5 days. We wanted to do a day trip to Waitomo and Rotorua but that seems like it would be a very long day and pricey as well. Our cruise ship will dock at Tauranga, and now we are looking at visiting Rotorua from there instead. But we did want to see glow worms. I was reading and it seems like there are glow worms all over NZ - can anyone recommend an "alternate" location where we could see glow worms that is closer to Auckland?
