title: An overview of mining in the Te Aroha mining district from the turn of the twentieth century until the start of the depression

authors: Hart, Philip

abstract: Apart from the mines owned by Edwin Henry Hardy, mining at Waiorongomai stagnated in the early twentieth century. During its first decade attention largely switched to the Tui district, with new treatment processes promising better results, but, as usual, raising capital was difficult and the government was asked to assist. A mining revival was constantly anticipated, especially by the local newspaper, and for the first time base metals were also investigated. Prospecting encompassed new areas, with the Mangakino Valley and the top of the mountain being investigated more thoroughly than previously.
In 1913, the battery was destroyed in a fire but was replaced. During that decade and the subsequent one, mining faded away to almost nothing, and only the onset of the Depression caused any revival.

title: Sediment aluminium content of Lake Okaro: 2021 monitoring survey

authors: Tempero, Grant Wayne

abstract: The application of aluminium salts such as polyaluminium chloride and aluminium sulphate has been widely used to assist in the remediation of eutrophic freshwater ecosystems. Aluminium binds to phosphorus, reducing its availability for phytoplankton growth, with the additional benefit that sediment phosphorus is reduced under anoxic lake conditions. Since 2013, alum (aluminium sulphate) has been applied twice per year to Lake Okaro to reduce dissolved reactive phosphorus availability. The lake’s annual Trophic Lake Index has decreased from 5.5 in the early 2000s to 4.5 in 2020. Alum dosing has resulted in the addition of 3.8 t of aluminium to the lake, however, the spatial distribution and sediment accumulation rate of alum derived aluminium has not been investigated.

The University of Waikato was contracted by the Bay of Plenty Regional Council to survey sediment aluminium concentrations in Lake Okaro to determine the distribution and accumulation of alum derived aluminium. In addition to sediment total aluminium content, the proportion of amorphous (non-crystalline) aluminium was assessed. Amorphous aluminium is the fraction of total aluminium able to adsorb dissolved phosphorus, sequestering it from uptake by phytoplankton. It was assumed that increased proportions of amorphous aluminium were primarily derived from alum dosing.

title: Transitioning from kōhanga reo to kura

authors: Hohepa, Margie Kahukura

abstract: This is a collaborative cross-sector research project involving a kōhanga reo (Māori immersion early childhood language nest) kura (Māori language immersion school) and university-based researchers. It focuses on tamariki (children) moving from kōhanga reo to kura classrooms and will examine the development of an 'akoranga whakawhiti', a transition programme that will be based at Te Kōhanga Reo o Ngā Kuaka in Hamilton. The over arching research question for this project is: Pēhea rā te āhuatanga me te kounga o ngā whakawhitinga mai i te kōhanga ki te kura mō ngā tamariki, whānau, kaiako me te hāpori? - What do effective transitions from kōhanga reo to kura look like, feel like, and sound like, for tamariki, whānau, kaiako and the community? The project aims to provide important new insights into learning and teaching in Māori-medium settings and into ways of enhancing transitions from Maori-medium early childhood education to Māori medium classrooms.
