Three of us are taking a 17-day tour of New Zealand finishing in Christchurch on March 11, 2013. We are considering extending our stay by 6 or so days but would like to go to one scenic, non-urban location to rest/bird watch/explore on foot. We would like comfortable, reasonable lodging that either provides food or is located within walking distance to food (we would be willing to cook our own if the accommodations had a kitchen). Since we plan to stay in one place, we thought pubic transport rather than car rental would be the way to go. We realize there are many beautiful places in South Island but any suggestions on location/accommodation/transport would be gratefully received.
