dc.description.abstract	The Institute for Radio Astronomy and Space Research (IRASR) of Auckland University of Technology (AUT) launched the New Zealand's first and only research capable radio telescope (WARK12M) near Warkworth which is located 60km north from Auckland 8 October 2008. We intend to use the WARK12M for both purposes of radio astronomy and geodesy. The WARK12M belongs to Australia and New Zealand SKA project and is providing valuable results in cooperation with Australian station. On the other hand, in the geodetic field the WARK12M became a network station of the International VLBI Service for Geodesy and Astrometry (IVS) and is participating in IVS regular sessions from the beginning of this year. The WARK12M mainly participated in IVS-R1 and IVS-R4 sessions as much as possible and is contributing to provide twice weekly Earth Orientation Parameter (EOP) results. In addition, we are coordinating the experiment together with Japanese VLBI station to provide ultra-rapid EOP result. We also intend to contribute to the geodetic and geophysical study in New Zealand. The WARK12M is collocated with a GNSS station (WARK) which belongs to PositioNZ network maintained by Land Information New Zealand (LINZ). The inter-technique (VLBI and GNSS) solution is capable of increasing reliability of the national geodetic infrastructure. Here we will introduce WARK12M and explain the great synergetic relationship between VLBI and GNSS that we aim in New Zealand and will show the first synergetic result at Warkworth. To determine the initial coordinate of our VLBI reference point, we conducted GPS survey in collaboration with the New Zealand Crown Research Institute, GNS Science and LINZ. In addition, we intend to show the recent results and discuss about noise sources such as the Ocean Tide Loading or Atmospheric Loading to influence geodetic observation at Warkworth.
