title: High performance aligned short natural fibre - Epoxy composites

authors: Pickering, Kim L.

abstract: Aligned short harakeke fibre (New Zealand flax) mats were produced using dynamic sheet forming, impregnated with epoxy resin, then pressed and cured on a compression moulder to manufacture composite materials. These composites were found to have significantly higher tensile properties than planar random oriented short fibre composites; the tensile strength (136 MPa) obtained for the composites is higher than any seen in the literature to date for short natural fibre composites. Fibre orientation was not affected by fibre content despite the higher processing pressure required and fibre orientation factors obtained from Modified Rule of Mixtures equations for Young's modulus and tensile strength were found to be similar.

title: Pest Fish Control - Fact Sheet

authors: Tempero, Grant Wayne

abstract: Due to their negative impacts on water quality and native biodiversity in New Zealand, regional councils have included a number of introduced freshwater fish species such as koi carp, rudd, brown bullhead catfish, goldfish, tench, gambusia (mosquitofish) and European perch (Figure 1) in their pest management plans. The Department of Conservation and regional councils undertake control and eradication programmes around New Zealand every year in order to contain their spread and reduce their impacts. Nearly all regions of mainland New Zealand have at least one of these species but they are most prevalent in the Auckland and Waikato regions. LERNZ has been researching the population ecology and capture methods of pest fish populations in order to develop efficient methods for their control.

title: Māori loanwords: a corpus of New Zealand English tweets

authors: Trye, David

abstract: Māori loanwords are widely used in New Zealand English for various social functions by New Zealanders within and outside of the Māori community. Motivated by the lack of linguistic resources for studying how Māori loanwords are used in social media, we present a new corpus of New Zealand English tweets. We collected tweets containing selected Māori words that are likely to be known by New Zealanders who do not speak Māori. Since over 30% of these words turned out to be irrelevant (e.g., mana is a popular gaming term, Moana is a character from a Disney movie), we manually annotated a sample of our tweets into relevant and irrelevant categories. This data was used to train machine learning models to automatically filter out irrelevant tweets.
