Waiteti (sometimes named Waititi)[1] was a passing loop on the North Island Main Trunk railway (NIMT) in New Zealand, built in 1939 to relieve congestion along a single track block, where the line rises steeply from Te Kuiti on a 1 in 70 gradient for 7 mi (11 km),[2] including curves of 8 ch (160 m) to 20 ch (400 m) radius.

[4] From its opening it was under central control from Te Kuiti signalbox.

[6] The work was done at the same time the loop at Kopaki was extended, the total cost for both being £19,000.

[10] Electrification came in 1988,[11] which allowed for more powerful locomotives, reducing the need for the passing point on the long gradient.

The loop was on the section of line from Te Kuiti to Puketutu, for which the Public Works Department had signed a contract on 9 March 1887 and which opened just over 2 years later.
