First of all, the route of the 267 m long "Motion Storwater Drainage" in the city of Auckland was optimized (radius 400 m) by engineers of the tunnel construction company Beton- und Monierbau GmbH and defined in a navigation equipment of the type SAS22. The system components - based on a gyro´compass MK20 and electronic hose levelling instrument - could be installed without any problems in the full cut heading machine with an outer diameter of 2.26 .

Gerhard Weithe, graduate engineer of the measuring division of Beton- und Monierbau, carried out the installation and initiation of the system, the startup of the machine and the instruction of the New Zealand engineers and machine operators on site. After only one week of training, the team had the ability to execute the complete system operation including control measurements independently and to navigate the TBM with very high precision through the unaccustomed curved drive. The support with adjustment of the measurement results, determination of machine drift and evaluation of log-data could be successfully assured per e-mail from Germany "around half the world". "With this technology, we are now leading in New Zealand," Mike Harker stated in view of future projects. There will surely be still a lot of work to do: alone the urban area of Auckland has an extension of 5,200 km² (!)...
