Little Squirts that Hang Out Around the Coast (Feb 12, 2013)
National Institute of Water and Atmospheric Research.
NIWA has created a new, colourful and intuitive guide to sea squirts found around New Zealand coasts and ports. Packed with photographs of 28 species, the guide is geared towards easy identification of sea squirts in the field and is a useful tool for keen underwater observers. The guide includes some of the recently arrived invasive species of sea squirt that have colonised our ports and harbours, as well as many benign native species. It covers species we're already aware of, so if you spot what you believe is a new one, please let the Ministry for Primary Industries know on their freephone 0800 80 99 66.

Thirteen Additional Plants Make List of Banned Species (Jul 26, 2012)
New Zealand Ministry for Primary Industries.
Under an agreement between government agencies, regional councils and the nursery industry, thirteen plants have been confirmed as pests and added to a list of species that are illegal to propagate, distribute or sell. The agreement - the National Pest Plant Accord (NPPA) - was created in 2001 to help prevent the spread of invasive plant species through the nursery trade or casual trading. All plants on the NPPA register are unwanted organisms under the Biosecurity Act 1993 and cannot be sold, distributed or actively propagated. Existing plants are, however, allowed on private properties. All listed plants are considered invasive species and threaten New Zealand’s existing plant life.
