Euler vectors for the motion of NZ relative to IGS14 for the periods July 1996 to June 1999 (in red) and July 2006 to June 2009 (in blue). (a) Distribution of Euler-pole ensembles. Contours show 95% confidence region. Continents are in light grey, plate margins77 are in solid black. NZ plate is hatched. (b) Close-up view of the Euler-pole distributions. Inset shows the distributions of the NZ/IGS14 angular velocities associated with the Euler poles. (c) Estimate of the probability that random, cross-site correlated noise in GNSS station velocities (cross-correlation coefficient is taken to be 0.1 and 0.9) is the sole factor determining the difference between Euler vectors inferred for the earlier and later periods (see main text for details). This figure has been produced partially using Generic Mapping Tools version 676.
