Correcting the links: Harold John Jenks

Harold Jenks, Fellow of the New Zealand Institute of Surveyors, was a member of the Tauranga Historical Society.

A lot of effort went into the mapping and measurement of this country.  A lot of it still goes unnoticed or ignored, although among the processes of colonisation the work of nineteenth-century surveyors was both intrusive and consequential[1]; they knew their work would have practical, permanent effect.  They were also, perhaps, of all colonisers the most aware of their own shortcomings.  Surveyors like Harold Jenks were modest characters.

By the twentieth century, when Harold arrived in New Zealand, a seventeen year old youth, occupation “fitter”, who had embarked at Southampton in 1924, he still found a quite astonishing scope and scale for physical challenge, intellectual adventure, and – it has to be said - error correction.  Even after twenty years of painstaking study and challenging fieldwork, he had to adapt his project, the Waikato Hydro-Electric Scheme, to the fact that a 7.65 foot discrepancy in the assessed level of Lake Taupo had been established[2].

The seven North Island networks of local mean sea level datums (LVDs) relied on by surveyors from approximately 1950 until 2016.  Lake Taupo can be seen near-centre of the Moturiki network.  Image: Toitū Te Whenua | Land Information New Zealand

Harold was equal to this.  In his memoir he says he “has forgotten now” how the construction plans for the “hydraulic structures” were adapted to the new, “identifiable and acceptable” [3] datum.  For him the great thing was confidence.  Plans could be made; great works could be engineered.  Fundamental to these plans and works was an accurate survey.

As a very young man, with few-to-no formal qualifications, on his own in a new country, Harold showed considerable confidence.  His long life (he was 101 when he died) saw his chosen profession change from one where a would-be surveyor took a cadetship, “serv[ing] under articles to a qualified surveyor”[4] to a time when only a university qualification would do.  But his experience as an articled cadet, “a rather rough school”[5], linked him more closely to the nineteenth-century surveyors.  They became the subject of his first book, Forgotten Men: The Survey of Tauranga and District 1864 – 1869[6], published by the Tauranga Historical Society in 1991.

Harold had joined the Society shortly after his retirement, when he and his wife Gwen left Wellington to re-settle in Mount Maunganui.  He was an active member: on the debating team that went to Rotorua to argue “That photographs are the best means of recording history”; leading a Society members' outing to see the Waikato power sites; distributing the Historical Review in Mount Maunganui; and eventually becoming one of three Vice-Presidents in 1990.  He thus came into contact with Alan Bellamy, who, like Harold, had made his way up the ranks of his chosen profession (rail transportation) and, on his retirement, joined the THS.  Alan had developed an interest in old photographs and printing work; his Society task at the time was to collate articles from Tauranga for eventual publication in the Review. The two men had a lot in common.istorical Society to publish the

 

 

 

 

Harold had already contributed a couple of well-crafted articles for the Review[7].  His next effort, a comprehensive account of the men who undertook the first surveys of Tauranga, had however grown well beyond the limits of a magazine story.  In 1988 Alan Bellamy got the Society’s approval to publish the manuscript, carefully illustrated with photographs and fold-out maps and documents, as a monograph costing $12 a copy: “pre-publication orders would be sought”[8]. 

Thus encouraged by Alan, Harold’s pride in his chosen calling found a means of impersonal expression:

But who were these men, the Kai-ruuri Whenua who first measured this land, appraised it, considered its access and ran the road lines; who planned and marked out the boundaries of the town lots and the farm areas; who laid down a pattern of development which still shows through clearly after the passage of 130 years?

What brought them to Tauranga, what experiences befell them while here and what became of them when their work was finished?

Very little has been written about them and only a few are known by name.

Local historical scholarship owes much to inquiries of this kind.  Writing from his perspective as an English-born, New Zealand-trained professional, the links Harold provides to the past evoke a sense of landscape that, as it was measured, confined by a history of chains and links, so became man-made, and subject to human error.  He also offers some account of older, equally human, understandings of topography, distance and land use[9]. 

Local historical researchers often find that these overlap each other.  They are not only linked; they invite us to consider the need for correction and a more reliable datum.  Harold would, I think, approve.
