Notes

*Resurrection - After being hit twice by major earthquakes, the city of Christchurch weighs up how to emerge from the rubble.

* Colour Morphs - New Zealand's flora and fauna can come in many shades - sometimes vibrant abnormalities surface and change the game entirely.

* The Beach - We meet the garrulous residents of the coastal fishing village of Ngawi: a truly uncut gem of kiwiana.

* On the Edge - In the wake of receding glaciers, climbers must find new routes up old peaks.

* The Microscopic World of lichens - The miniature forests of the often-overlooked lichen hold biological secrets and some surprising uses.
