Police believed their 2002 eradication programme would wipe out about 40 per cent of the national crop, its national coordinator Detective Senior Sergeant Don Lee said.[1] Northland, the eastern Bay of Plenty and the Coromandel were the biggest problem areas, though Waikato, Gisborne and other parts of the Bay of Plenty had also yielded big crops of high-quality cannabis.[1]

Officers destroyed 35,000 plants in the Bay of Plenty and 19,500 in Northland during March, plus 13,000 across Rotorua, Taupo and Tokoroa.[1] About 500 plants growing among maize and on Matakana Island in Tauranga Harbour were seized, a shotgun was taken from a grower camped by his crop at Te Puke, and a search of a Papamoa house found 50 plants growing under lights alongside stolen computers and a mountain bike.[1]

In previous years police estimated they had wiped out about 40 per cent of the crop by aerial spraying and uprooting, and with a month of the season still left Lee expected the same figure again.[1] Growers were planting smaller plots in bush clearings, and police said hydroponic setups were expensive and carried serious consequences for growers who were caught.[1]
