Waiheke Island, New Zealand. Limestone carvings appear throughout the island. Here, a Maori gentleman touches up a piece that greets visitors to a Maori retreat that overlooks a quiet beach.

This particular sculpture is a receptacle for gifts (coins) from those who visit the retreat and want to contribute for what they use. Another, nearby, calls upon ancestors to protect guests and haunt any who do harmful things while on premises. Sun, wind, and rain actually strengthen and smooth the artworks over time, he explained. But sometimes a crack occurs that needs a bit of love and attention.
