Tongan Ngatu — Tapa Cloth and Kupesi Tradition

Ngatu — Tonga Tapa Kuo'osi

The Tongan ngatu (tapa cloth) tradition — the production of the distinctive Tongan tapa cloth in cooperative women's groups (kautaha) using the kupesi (carved relief tablet) rubbing technique to produce the characteristic ngatu patterns, whose large-format sheets (some up to 100m long for ceremonial purposes) represent the most ambitious bark cloth production tradition in Polynesia. The Tongan tapa maker reads the correct ngatu thickness through the same hold-and-translucence assessment as Samoan siapo (CRAFT-0674) but calibrated to the Tongan preference for slightly thicker, more opaque ngatu.

Primary Materials: Paper mulberry bark (hiapo — same species as Samoan u'a); kupesi carved tablet (for the pattern rubbing)
Primary Tools: Wooden beater; kupesi tablet; the hold-and-translucence (3 seconds)
Process Overview: Hiapo bark beaten; hold-and-translucence assessed; sheets joined; kupesi pattern rubbed; koka dye applied; complete ngatu
