No other advantage was gained by the step.

A statute was passed in England in 1817 authorizing the trial and punishment of persons guilty of murder and other crimes in certain savage and disturbed countries, amongst which were specified New Zealand, Otaheite, and Honduras.

Two others, in 1823 and 1828, gave the Australian courts jurisdiction over Whites in New Zealand.
One White ruffian was actually arrested in New Zealand, taken back to Sydney, and executed.

But this act of vigour did not come till the end of 1837.

Then the crime punished was not one of the atrocities which for thirty years had made New Zealand a by-word.
