title: Harry Kenrick: the first warden of the Te Aroha mining district

authors: Hart, Philip

abstract: Because of his improvident father, Harry Kenrick left England for the Victorian goldfields before moving to the South Island of New Zealand. In 1865, he settled in the West Coast to begin a lifetime career of working for the government. In addition to his official duties, he was involved in mining and assisted to develop the district, becoming involved in disputes that foreshadowed his experiences at Thames.
Appointed as resident magistrate for Poverty Bay in 1877, his work was praised, as it had been on the West Coast, but two years later he was abruptly moved to Thames to become both magistrate and warden after the forced resignation of his predecessor, William Fraser. The latter’s career is examined, as is how his clique hated Kenrick for replacing him; but most residents welcomed a man whose decisions were seen as fair and just. Fraser retained support amongst many in the community, becoming mayor and then a member of parliament, but continued to snipe at Kenrick, supported by a small number of malcontents, who made his life difficult.
In his determination to make his subordinates perform their duties satisfactorily, Kenrick provoked conflict with Hugh McIlhone, Inspector of Miners’ Rights, and James Monteith McLaren, Inspector of Mines. They were supported by two prominent Thames residents, Louis Ehrenfried, a brewer and local government politician, and George Nathaniel Brassey, a solicitor, who spent years trying to undermine Kenrick for their own personal advantage. In 1880 and 1885, two petitions to remove him failed miserably, as his reputation both locally and with the government and its officials had risen steadily. 
Kenrick improved mining regulations and enforced them fairly, as even some who lost cases accepted. At Te Aroha, after some initial criticisms he became popular because of his efforts to be fair to all who came before him in court and his assistance both to mining and to the development of the district. His efforts to assist Maori made him popular with them as well, and when he died, prematurely, he was deeply mourned by both Maori and Pakeha.

title: Habituation and Dishabituation of Physical Activity

authors: Crawford, Demelza

subjects: habituation

abstract: Three experiments with single subject research designs were conducted to see whether habituation occurred as human participants completed physical activity. Experiment 1 had an arrangement where participant’s rates of stationary cycling were recorded throughout 20 minute sessions. Instead of habituation, stationary cycling rates increased over time, likely to be due to a rule that controlled behaviour derived from previous reinforced responding in the same setting as the experimental context. Experiment 2 was arranged similarly to Experiment 1 with an added concurrent task to disrupt the behaviour chain causing the rule-governed behaviour seen in Experiment 1. Despite this concurrent task, rates of stationary cycling again increased due to rule-governed behaviour. Experiment 3 had stationary cycling rates associated with a salient reinforcer that could lose its effectiveness to reinforce over time and thus habituate. Instead, Experiment 3 resulted in stable rates of stationary cycling consistent with task adherence, a rule-governed behaviour. With the failure of habituation to predict the results of this study, they are instead discussed from the more applicable perspective of motivating operations.

title: Monitoring te mana o te wai: Intergrating an indigenous cultural health index with conventional biomonitoring tools for improved freshwater management

authors: Edgecombe, Shana Jade Te Iaa Tarere

subjects: Freshwater

abstract: Globally, there are universal efforts to quantify and address human impacts on ecosystems. In particular, changes in land use and river regulation have led to drastic declines in stream and river ecosystem health. These human impacts are driving the global freshwater biodiversity crisis and degrade ecosystem services provided by aquatic habitats. In Aotearoa New Zealand there is widespread concern about the state of our Nation’s freshwater ecosystems. Coupled with a renaissance in Māori culture, there has been a drive to develop indicators that help articulate cultural values, assess ecosystem health from a cultural perspective, and provide greater agency for Māori in environmental monitoring and management. In my thesis, I sought to integrate an established cultural monitoring framework with conventional biomonitoring tools for improved freshwater management. I hypothesized that using a suite of monitoring approaches would help detect the impacts of human land use on stream ecosystem health, and that cultural indicators would be consistent with conventional measures in diagnosing land use impacts. I also hypothesized that there could be discrepancies between cultural monitoring and conventional approaches, as each represent different perspectives and ways of knowing streams and rivers. 
To test my hypotheses, I selected ten stream sites across the catchment of the Kuratau River, a major tributary of Lake Taupō. Based on River Environment Classification land cover types, I used a balanced study design with five sites draining indigenous forest, and five sites draining pastoral land. I measured key stream physicochemical properties and collected water samples for determination of nutrient concentration and faecal coliform counts. I also characterised instream and riparian habitat. I collected benthic macroinvertebrate samples and sampled water for environmental DNA (eDNA) to assess different facets of biodiversity. I measured decomposition using the Cotton Strip Assay and quantified periphyton biomass using a portable fluorometer. In combination with these approaches, I also used a Cultural Health Index, an established cultural monitoring framework that assesses three components: customary significance, taonga species/mahinga kai (food gathering), and the Cultural Stream Health Measure (CSHM) to assess identified attributes for stream health.
I found that pastoral land uses lead to a decline in stream ecosystem health when compared to sites draining indigenous forest. Pastoral sites had higher specific conductivity and concentrations of total nitrogen and nitrate. Habitat variables changed, with increased sedimentation and more degraded riparian zones in pastoral streams. Decomposition rates as measured by the cotton strip assay increased in the pasture sites, which was likely a response to increased nutrient availability. There were shifts in macroinvertebrate composition, with key indicator taxa for Indigenous forest sites including pollution-sensitive mayflies and stoneflies. Total taxa, EPT (Ephemeroptera, Plecoptera, Trichoptera), and aquatic insect richness all significantly declined in pastoral sites. Increases in primary production were less pronounced, but did increase alongside abundances of grazing caddisflies and snails in the sites draining pastoral catchments. 
The Cultural Health Index indicated that sites in the Kuratau River catchment had customary and mahinga kai values. CSHM responded negatively to pastoral land uses, and the effect size it described was congruent with other responses. The CSHM was strongly correlated with an indicator of riparian habitat condition (the Riparian Condition Index) and had weak negative correlations with sedimentation and stream temperatures. The CSHM was not correlated with macroinvertebrate indices, which may have been because of the relatively few sites sampled, the narrow impact gradient in the Kuratau catchment, and the lack of temporal replication. However, cultural monitoring approaches should be seen to complement conventional environmental monitoring methods for assessing freshwater and not be expected to duplicate them. The strength of the Cultural Health Index approach comes from establishing Māori agency to assess the environment through a Te Ao Māori lens, and to support and foster inclusion for tangata whenua epistemologies in environmental monitoring and resource management. Future research should consider greater hapū involvement and further explore the mechanisms driving changes in stream health and biodiversity.
