White bait spawn in the long grass, carex and rushes in the estuarine areas of rivers. Some years ago a regulatory move was made to stop cattle grazing in these areas and that has had a positive effect to protect the spawn. The adults are the ones in trouble with pollution of slow moving drains and streams which are their habitat. A lot of this pollution is from towns, most towns being in the coastal belt. As an example every single stream and drain around Rangiora is now polluted with contaminated storm-water, thirty years ago only one stream was.
