On 1 Jan, the Post & Telegraph Department (which operated New Zealand’s coast stations) was renamed the New Zealand Post Office (Post Office Act – 1959), but it remained a government department.
Staff have been occupied with re-cabling and jumpering as a result of the re-routing of all the circuits that previously went to Auckland via the undersea cable to St Heliers being now routed via Tamaki-Ellerslie. The underwater cable to St Heliers is literally on its last legs and will preferably not be repaired again.
Authority for the reconstruction of Auckland Radio has been obtained and the equipment is to be replaced with modern equipment suitable for unattended operation.
The annual calibration of the old Marconi DF receiver was carried out during a recent spell of cold but fine weather. The spread of houses into what, a year or two ago, was farmland, has caused the loss of more of our test pegs and caused a bit of head-scratching at times. The calibration of the sea sectors was held up occasionally by fog and the need to top trees on the cliff edges. No news yet about bringing the Telefunken set into use.
The working frequency on our main marine transmitter was changed from 524 kc/s to 432.5 kc/s on 8th June for a month’s trial. This was not a happy choice however, as the fifth harmonic of this new frequency appears on 2162.5 kc/s on the small ships to Auckland Radio frequency. Putting traps in the aerial feeders at the transmitting station reduced the level of this harmonic at the receiving station to just under ten microvolts, a tolerable level on this service.
It looks like the tech is probing the high voltage parts with a neon stick to ensure the volts were dead prior to working on the transmitter. He seems to be keeping his other arm behind as we were trained to do to avoid getting plated.

At 4.05 pm on 13 June, Auckland Radio ZLD received a PAN (Urgency) radiotelephone message from the coastal freighter MV Maranui, after the vessel’s cargo of bulk wheat shifted in a severe storm:
APPROXIMATELY 25 MILES EAST OF MERCURY ISLAND. ARE THERE ANY VESSELS IN VICINITY? LIST IS INCREASING.
Another call was made to Auckland Radio ZLD at 5.03 pm:
MAYDAY MAYDAY FROM MARANUI. POSITION 36.48 SOUTH 176.25 EAST. LISTING BADLY, REQUIRE IMMEDIATE ASSISTANCE.
A minute later:
CLEARING LIFEBOATS AND LIFERAFTS NOW IN CASE THEY ARE NEEDED.
ZLD contacted the 8160 GRT Swedish freighter Mirabooka, which was approximately eight miles from Maranui.
Through outstanding seamanship in extreme conditions, the captain of Mirabooka picked up six crew from Maranui‘s liferaft, but nine others were swept away to their deaths.
In 2005, Maranui‘s resting spot was found when a trawler’s net snagged and brought up a radar scanner at 36° 42′ S, 176° 25’ E. (See more at maritimeradio.org)
