The 1886 Tarawera Eruption – Precursors

Sunday, July 30th, 2006

The 120th anniversary of the eruption of Mt Tarawera on the 10th June 1886 was widely remembered earlier this year.

Vulcanology was poorly understood at the time, so it’s not surprising that a series of events which had occurred 5 years earlier were not fully appreciated, despite being widely reported in the nation’s newspapers during 1881.


Gisborne TMX – Part 3

Saturday, July 29th, 2006

Maintaining the manual toll boards of the 1970s was moderately labour-intensive. Installation obviously involved considerable labour, as circuits were hard-wired to modules which were repeated at regular intervals around the board. However, once installed, the various components were highly reliable considering the mechanical forces involved in day-to-day operation.

Gisborne TMX – Part 2

Wellingtonians are shivering under yet another southerly blast today. July 2006 looks set to make additions to the weather record books, with the regional council announcing that new July rainfall records may be set in both Wairarapa and Wellington.

Gisborne TMX – Part 1

Thursday, July 20th, 2006

The Gisborne TMX (Toll Manual Exchange) was located on the first floor of the “new” exchange building in Read’s Quay when I worked there in the late 1970s.

In keeping with the ‘design for expansion’ philosophy of the time, the “toll room” (as we called it) was a huge well-lit room with Post Office standard linoleum flooring. Entering through the double doors near the top of the stairs, a visitor walked past the Toll Manager’s office and across an expanse of floor with the ubiquitous metal lockers to the left, past a few well-tended pot plants to the toll board and supervisors’ desks. On the right, near the supervisor’s desks were the standard time-book desks where staff signed in and out as they carried out their shifts.
