Here’s an environmental message “published” by Heather Martin at Tauroa Farm.
If you’d like to view it live, it’s best seen from Te Mata Peak (only for a few more days), along the final stretch of road between the Gallipoli pine and the summit viewing platform. Best not to look while driving!
For you gardeners and horticulturalists, the letters are mustard, the background is flax (linseed).
