The short answer to this question is 'local stone'. For anywhere the first buildings are needed, almost by definition, items such as roading and transport infrastructure are absent or in their infancy.
In Central Otago, schist would be the stone type; in Dunedin the local supply of volcanic stone ensures their easy use; in Oamaru there are both limestones ofo several sorts, and some volcanic stone as well.
Quints stone.
The stone used to build the first buildings in the South Island of New Zealand is commonly known as schist. Schist is a type of metamorphic rock that is abundant in the region and was commonly quarried for construction purposes.
Both quarry stone and natural stone were used in buildings in the South Island. One of the natural stones was schist, which is a flat-faced stone, and very suitable for buildings. Other stones used were volcanic rock (Dunedin Railway Station), and limestone from Oamaru.

No. Whilst Kangaroo Island was the first region settled in South Australia, it was not discovered first. Kangaroo Island was discovered by Matthew Flinders in 1802. Various early Dutch explorers ventured into South Australia's western coastline during the 1600s. South Australia could be said to have been discovered in 1627, when Thijssen recorded the first observations of the South Australian coast.

Rakiura/Stewart Island. It is south of the South Island, and hence at a higher latitude.
Reefton, in the South Island.
He linked Stewart Island to the bottom of the South Island,not realising it was,in fact,an island.
