The Judicial system here and in many other jurisdictions requires this oath or similar to be sworn by a witness giving evidence before the court.

It is merely to most, an aspirational goal that is malleable to a point of flexibility where the real truth will disappear in a fog that would suspend operations at any Airport.

Lets take what the Interwebby will relate when asked the time it took to build the State Highway One Detour via Transmission Gully.
“Seven years and six months” Utter B S?

Over a century ago thinking people began to consider the twenty seven Km alternative to the dangerous accident prone old SH 1 along the coast now designated SH 59.
During the closing months of WW2 when there were thousands of US military using New Zealand as a forward base and rest and recreation zone for the millions involved in turning back the Japanese Empire forces that after beginning conquest of China and Mongolia in search of raw materials in the 1930s turned south and west to expand their Empire to include almost the entire Far East with the attack on Pearl Harbour designed to cripple the US Navy.

Now those US forces had almost unlimited resources and confronted with the almost third world transit between the Capital with its port and the more suited military areas of Linton, Ohakea for training and accommodation very soon became aware of the real value of the Transmission Gully option and offered the then Labour led Government cost free a build of a highway?
A route that only trims around ten minutes off the old road but when multiplied by the current estimated 25 000 movements a day soon becomes a number that could impress a neanderthal.

Finally opened in 2022 by a bunch of hypocrites who had done as much as possible to thwart construction but were more than satisfied to turn up for the beers and buns and handing a bunch of Koha to rename the road Te Aranui o Te Rangihaeata to still never designated wonderful part natives. the cost is recorded at 1.25 Billion NZ$.

Ninety years earlier it was offered for NZ$0.
