The main entrance to Tauranga Harbour was recently deepened by over 3m, to accommodate ever-larger container vessels.
Two weeks ago, as part of a regular bi-annual survey of shorebirds run by Birds NZ, I visited Panepane Point on Matakana Island, which forms the western side of the main entrance to Tauranga Harbour. I was shocked to note the erosion of maybe 20m of the coast, almost certainly due to the deepening of the channel.
Panepane Point used to be an important breeding site for the northern New Zealand dotterel charadrius obscurus, an endemic shorebird which is only recovering thanks to the efforts of volunteers. I would expect to see four or five breeding pairs, but on this visit, I spotted three, possibly four birds, none showing signs of breeding, though it is the height of the breeding season.
Before wishing yet more port development on Tauranga, have a look at some of the issues.
Yes, move Auckland port, but don't forget the environment, it's the only one we have.
