Earth tremors being felt around Christchurch's new Prestons subdivision are of the good variety, its developers say.

A 40-tonne three-sided elliptical roller, known as Thumper, has been compacting soil over a 25-hectare plot on the 203-hectare Redwood development to prevent possible liquefaction.

Ngai Tahu Property development manager David Schwartfeger said the using land-stabilisation machine would bring all the land at Prestons to technical-category 1 (TC1) standard.

The majority of the development was already classified TC1 and this remediation was to bring localised areas of TC2 land up to the higher standard, he said.

Compacting work was expected to take about 20 weeks.
