The 1978 Christchurch International (sponsored as the Colgate International) was a tennis tournament organised for female professional tennis players. It was the 3rd edition of the WTA Christchurch tournament, and the 1st since 1972, as it was cancelled during 1972–77, and this was the first time the event was a professional tournament and offered prize money and ranking points, upgraded from the non-tour event in the first two editions.
