Disable zoom on touch screen

The map on this page is defined by:
[leaflet-map zoom=”5″ height=”450″ lat=-40.83824 lng=173.7252058 !dragging]
[leaflet-marker lat=-37.72 lng=175.12]Auckland [/leaflet-marker]
more markers.

When viewed on a mobile, the !dragging operand prevents the user from scrolling the map.
However, it is still possible to zoom (two-finger) the map in and out. Is there any way of making the map completely static.

Andy
