An alleged boss of the Wellington Nomads hid a stash of thousands of dollars worth of methamphetamine in cemeteries, a court has been told.

Paul Peter Mawana Rodgers, known as Porky Rimene, has pleaded guilty to supplying meth between July 2009 and February 2011, offering to supply the drug, conspiring to obstruct the course of justice, money laundering and taking part in a criminal group.

He is accused of distributing more than three kilograms of meth - with a street value of $3 million - into the Wellington region.

An unnamed witness told the High Court at Wellington on Monday that Rodgers had so many places to bury drugs and money that it was hard to keep track of them, Fairfax reported.

The witness said he buried drugs and money at sites around Wellington and Wairarapa, including at a private urupa or cemetery in Masterton.

A groundsman at Riverside Cemetery in Masterton also found a container of about $7000 worth of meth.

At one stage a bulldozer working on a public track displaced a buried container and they had to use a hired metal detector to find it.

The witness said Rodgers told him he would be buried if he did not find the drugs.

Rodgers disputes having a leading role in the drug dealings.
