1. Kerosene Creek 2. Wairua Stream
1. Kerosene Creek First on our list of hot pools in Rotorua is the world-famous Kerosene Creek. 35 minutes from Rotorua and down a gravel road will take you to the thermal pool and waterfall at Kerosene Creek. The creek is popular not just for its geothermal activity but its beautiful surroundings. Location: 28km south of Rotorua. Take State Highway 5, then travel about 2km down Old Waiotapu Road. 2. Wairua Stream Wairua Stream is a bit harder to get to as you have to get a boat across Lake Tarawera, making it a local’s paradise. It is near Te Rata Bay and is one of the most picturesque hot pools near Rotorua. Location: About 25 minutes out of Rotorua down Spencer Road, Lake Tarawera. By boat, launch at Stoney Point and head straight across Lake Tarawera to the headlands on the right of Mt Tarawera. Go straight through these headlands to where the lake opens. Steer gently to starboard and make for the only beach in this area. 3. Wai-o-Tapu / The Bridge / The Secret Spot When it comes to Rotorua hot pools, it does not get more popular thank this one. Funnily enough, it is supposed to be a secret. Get the remnants from the Wai-O-Tapu geothermal attraction by bathing in the hot pool formed by the hot Wai-O-Tapu stream meeting the cool river. It’s a thermal pool, completely natural and completely free! Location: Just outside the Wai-O-Tapu geothermal park (under the bridge). 30km south of Rotorua just off State Highway 5. -

Here, new whole-rock and microanalytical major and trace 25 element data from andesite-dacite lava flows are integrated with previous studies and existing 26 isotopic data, and placed within the framework of a high-resolution chronostratigraphy for 27 Ruapehu volcano (southern Taupo Volcanic Zone, New Zealand). The geochemical evolution 28 of lavas erupted over the ~200 kyr lifetime of the exposed edifice reflects variable degrees of 29 fractionation and systematic changes in the type of crustal assimilation in the Ruapehu 30 magma system. Lavas erupted from ~200–150 ka have previously been distinguished from 31 those erupted <150 ka based on Sr-Nd isotopic characteristics, which indicate that the oldest 32 lavas were sourced from magmas that assimilated oceanic crust. -
Protecting an Icon Managing Sources of Diffuse Nutrient Inflow to Lake Taupo, New Zealand Abstract Introduction Mandate for Acti
Diffuse Pollution Conference, Dublin 2003 1C Water Resources Management PROTECTING AN ICON MANAGING SOURCES OF DIFFUSE NUTRIENT INFLOW TO LAKE TAUPO, NEW ZEALAND Tony Petch1, Justine Young1, Bruce Thorrold2 and Bill Vant1 1Environment Waikato, PO Box 4010, Hamilton East, New Zealand 2Dexcel Ltd, Private Bag 3221, Hamilton ABSTRACT Lake Taupo is a large, near pristine lake in New Zealand, highly valued for its clear blue waters. Increasing loads of nitrogen from the surrounding catchment threaten lake water quality. A management proposal is presented that promotes a sustainable development pathway for the lake community thereby protecting the lake for all New Zealanders. A community change process to protect the environmental, economic, cultural and spiritual values of a lake is described Keywords: Community, economy, Lake Taupo, land use, management, nutrients, policy, water quality INTRODUCTION Lake Taupo is the largest lake in New Zealand (area 620 km2, mean depth 95m). It is highly valued for its crystal blue water and dramatic vistas. These features provide the basis of an international tourist mecca and a world-class trout fishery as well as an important local recreation area and preferred retirement location. The lake is also important spiritually and culturally to the local indigenous people, Ngati Tuwharetoa. Lake Taupo’s excellent water quality is derived from extremely low levels of plant nutrients and phytoplankton. Unlike many other lakes, nitrogen availability rather than phosphorus limits phytoplankton growth in Taupo. Increased nutrient flows, especially nitrogen, from intensifying rural land use and urban growth in the catchment promotes algal and phytoplankton growth and threatens water clarity and the excellent water quality of the lake. -
Over the Years
OVER THE YEARS A HISTORY OF THE RURAL COMMUNITY HALLS IN THE ROTORUA DISTRICT FOREWORD Nau mai, Haere mai, There are nine rural community halls in the Rotorua District, at Broadlands, Kaharoa, Mamaku, Ngakuru, Ngongotaha, Okareka, Reporoa, Rerewhakaaitu, and Waikite. Volunteers have driven the development and maintenance of these vital community facilities, which have been the focus for community functions and gatherings for many years. In 2001, Rotorua District Council awarded certificates of appreciation to many of these volunteers for their tireless efforts to sustain the upkeep of their local halls. This booklet was commissioned by the District Council to record the history of Rotorua’s rural halls, for both archival and community interest. Information was compiled in the latter months of 2002 by Marlana Maru, a Year 2 Bachelor of Applied Social Science student from the Waiariki Institute of Technology. RDC Social Research Officer Paul Killerby undertook additional editing and formatting. Marlana and I would like to thank the many local informants whose memories and impressions contributed to this booklet. In particular we would like to thank Barbara Blackburn, Peter Blackburn, Andy Burnett, Mary Burnett, David Fleet, Lyn Fleet, Maxine Greenslade, Triss Hill, Wally Hope, Marie Jepsen, Noeleen Martelli, Verna Martelli, Pam Murray, Jim Nicholson, Norman Reichardt, Rei Reichardt, Arthur Roe, Don Sandilands, and Chris Stevens. We would welcome any further background information on the halls listed in this booklet, which will be recorded and utilised in any further update of the publication.

This upheaval was described, in a report, by Mr. Allard, who was in charge of some drilling operations for petroleum in the neighbourhood at the time, as follows:- " Halfway between Mempakal and Lambedan, on the 21st of September, inl the afternoon, a small island was formed. Some natives were out gathering oysters, and noticed a good many bubbles rising, after which a gradual upheaval took place, and went on all night, forming a hill of about 200 yards by 150 yards, and 50 to 60 feet high. It seems to consist of nothing but slatey-looking clay, with a few sandstones in it, exactly similar to what we have been boring through. -
Auckland Regional Office of Archives New Zealand
A supplementary finding-aid to the archives relating to Maori Schools held in the Auckland Regional Office of Archives New Zealand MAORI SCHOOL RECORDS, 1879-1969 Archives New Zealand Auckland holds records relating to approximately 449 Maori Schools, which were transferred by the Department of Education. These schools cover the whole of New Zealand. In 1969 the Maori Schools were integrated into the State System. Since then some of the former Maori schools have transferred their records to Archives New Zealand Auckland. Building and Site Files (series 1001) For most schools we hold a Building and Site file. These usually give information on: • the acquisition of land, specifications for the school or teacher’s residence, sometimes a plan. • letters and petitions to the Education Department requesting a school, providing lists of families’ names and ages of children in the local community who would attend a school. (Sometimes the school was never built, or it was some years before the Department agreed to the establishment of a school in the area). The files may also contain other information such as: • initial Inspector’s reports on the pupils and the teacher, and standard of buildings and grounds; • correspondence from the teachers, Education Department and members of the school committee or community; • pre-1920 lists of students’ names may be included. There are no Building and Site files for Church/private Maori schools as those organisations usually erected, paid for and maintained the buildings themselves. Admission Registers (series 1004) provide details such as: - Name of pupil - Date enrolled - Date of birth - Name of parent or guardian - Address - Previous school attended - Years/classes attended - Last date of attendance - Next school or destination Attendance Returns (series 1001 and 1006) provide: - Name of pupil - Age in years and months - Sometimes number of days attended at time of Return Log Books (series 1003) Written by the Head Teacher/Sole Teacher this daily diary includes important events and various activities held at the school. -

Regional resistivity measurements and fluid chemistry surveys suggest that the Reporoa system is a lateral outflow of hot water from the Waiotapu Geothermal System to the north-east. A deep exploratory drillhole, encountered a sequence of lacustrine sediments, volcanic, tuffaceous and ignimbritic rocks. The well was discharged in October 1966, but was shut down after 5 hours during which time wellhead pressure fell from to Downhole temperatures in were measured after 47 days of heating and showed a significanttemperature inversion between and which is interpreted to be caused by hot water at about depth flowing above a cooler water influx.

Large-scale mass-wasting processes following the 232 CE Hatepe Eruption of Taupo Volcano, New Zealand - Sedimentary features and dispersal of reworked Taupo Ignimbrite in the Ongarue River valley Anke Verena Zernack and Jonathan Noel Procter Volcanic Risk Solutions, Massey University, Palmerston North, New Zealand ([email protected]) The 232 CE Hatepe Eruption of Taupo Volcano, New Zealand (also referred to as Taupo Eruption), was one of the most violent and complex silicic eruptions worldwide in the last 5,000 years. The pyroclastic sequence was subdivided into 7 distinct stratigraphic units that reflect diverse eruption mechanisms with pumice fallout unit 5 (Taupo Plinian) and unit 6 (Taupo Ignimbrite) contributing the largest volumes, an estimated 5.8 km3 and 12.1 km3DRE respectively. The non-welded Taupo Ignimbrite was emplaced by a highly energetic flow over a near-circular area of 20,000 km2 around the vent, reaching distances of 80±10 km. It consists of an irregular basal layer and a thicker pumice-dominated main unit containing varying proportions of pumice clasts, vitric ash and dense components, overlain by a thin co-ignimbrite ash bed. The main ignimbrite unit shows two distinct facies, a landscape-mantling veneer deposit that gradually decreases from 10 m proximal thickness to 15-30 cm distally and a more voluminous, up to 70-m thick valley-ponded ignimbrite that filled depressions and smoothed out the landscape.
