We will be in NZ in April and May for about 7-8 weeks. This is our third trip to NZ having done all the tourist highlights of the country in the past two visits. We are traveling with our 9 year old and would prefer to do absolutely peaceful/uncrowded locations this time around b/w Auckland and Lake Hawea/ Queenstown for a week at a time - places that offer 4-5 hours marked treks/walks from thereon that we cld indulge in daily. Love being anywhere around lakes/waterfalls. Will be self - driving and probably stay at self contained holiday homes/motels. Would appreciate suggestions for off-beat yet easily drivable (sealed roads)/accessible destinations?
