title: Potential Lake Rotorua scenarios

authors: Gibbs, Max M.

abstract: Lakes need weeds, good ones (native species) not bad (invasive exotic species), although even exotic species are better than no weeds. Without aquatic macrophytes, a lake can become phytoplankton dominated with low clarity and high chlorophyll concentrations, a condition from which it is difficult to recover. The challenge is to manage the macrophytes to the advantage of the lake to obtain the highest practical water quality that is acceptable to lake users, within the financial constraints of a rates-based budget.
Lake Rotorua has sufficient surface area and depth that macrophytes, by themselves, are not likely to control water clarity and phytoplankton growth. However, their management may be a critical factor in the restoration of Lake Rotorua. In this talk I look at potential scenarios associated with managing aquatic macrophytes in Lake Rotorua. With the availability of a weed harvester dedicated to the Te Arawa/Rotorua lakes, there are a number of options that can be applied to Lake Rotorua that would be beneficial to the lake and the people who use the lake. For example, the weed harvester can be used to mow
the weed beds to remove part of the nutrient load from the lake and thus improve the lake water quality. The Lake Rotorua Action Plan is looking to reduce the N load on the lake by an additional 50 t y-1. Weed harvesting has the potential to achieve this. Removal of the tops of surface-reaching macrophyte beds around some stream mouths may improve
trout fishing for anglers while maintaining the habitat that the trout need in shallow water. Clearance of boat ramps and maintenance of lake access are obvious applications. So is the mowing of the large areas of macrophyte beds adjacent to Rotorua city lake front to reduce plant break-off in wave action and thereby reduce the incidence of macrophytes washing ashore. These are just some of the potential Lake Rotorua scenarios.

title: Help wanted in New Zealand: The ANZ Bank job advertisement series

authors: Silverstone, Brian

subjects: help wanted

abstract: The ANZ Bank publishes a monthly count of the number of job advertisements appearing in New Zealand newspapers and, more recently, internet sites. It is New Zealand’s de facto vacancy or help-wanted series. Apart from its role in economic commentaries, there is very little published research using this data. This paper is a preliminary attempt to remedy this omission. It covers descriptive aspects of the ANZ job ads series including the vacancy rate, the hiring rate, regional characteristics and proxy vacancy series. This is followed by an outline of the vacancy-unemployment (Beveridge curve) and hiring frameworks and some initial econometric work. Overall, the paper highlights the importance of the vacancy rate and the hiring rate in assessing labour market conditions in New Zealand.

title: Secular schools, spirituality and Maori values

authors: Fraser, Deborah

abstract: New Zealand has had free, state, secular education since 1877, but just what is meant by secularism is changing. Since the 1980s the growth of Maori education initiatives has mushroomed and these place emphasis on Maori values and beliefs, including spirituality. In addition, in 1999 a definition and statement on spirituality appeared in the health and physical education national curriculum document. This statement referred to values, beliefs, meaning and purpose. It also incorporated a Maori model of well‐being which places the spiritual alongside other dimensions of humanity. This article explores the concept of spirituality in secular schooling in New Zealand. Some influences from Maori culture are explored with particular reference to values, ethical decision‐making and spirituality. Interviews with Maori teachers highlight how moral decisions often reflect spiritual beliefs and practices. It is argued that schooling has a moral obligation to reflect indigenous values if understanding, respect and cultural identity are to be promoted and cherished. It is also suggested that spirituality challenges what we have traditionally considered as learning at school.
