gradually to half that height on the coastline." And again: “ Toward 
the east My Parengarenga Harbour] there is a tendency to form tablelands 
400 ft. sea-level." Bell and Clarke (87, p. 614) suggest 
that a к TR about 1,000 ft. high that occupies a relatively consider- 
able area in the extreme north of New Zealand is the remnant of a pene- 
plain. Lignitic bands occur 2 the gus of Pleistocene sands that back the

Smith (72, pp. 403 and 407) has also traced the 15 ft. raised beach at 
various points in the Hauraki Gulf and Bay of Plenty. Hutton (6, p. 23) 
was the first to note this strand-line at Thames. According to Cussen 
(78, p. 404), an old beach 17 ft. above sea-level occurs at Maukoro, in the 
Hauraki Plain, about eighteen miles from the sea. Other raised beaches 
up to 100 ft. high have been recorded at several points between Auckland 
and East Cape. Beaches 25 ft. high occur near Thames (45, p. 29) and 
Tauranga (114, p. 212); at Cabbage Bay, 80 ft. (28, p. 70); north of 
Cabbage Bay, up ie 70 ft. (42, p. 61); at Waihi Beach and Orokawa, near 
Waihi, up to 50 ft. (48, p. 30); and at Te Kaha Point, 50—60 ft. (17, p. 199). 
At Opotiki is а tableland 100 ft. above the sea, and ac cording to Smith 
remnants of beaches from 80ft. to 100 ft. high occur at intervals from 
East Cape to Tauranga and along the east side of Hauraki Peninsula 
(72. pp. 406-8). 
Another group of raised beaches is represented by the terrace at the 
back of the Town of Thames, 150-175 ft. (28, p. 38), at the mouth of 
Kauaeranga River, and for several miles along the east side of Hauraki

'est of Tauranga, and farther south-east in the Te Puke district, these 
beds slope gently upward to a plateau which rises regularly to more than 
1,000 ft. Towards the sea this surface is deeply incised by the streams and 
dissected by their numerous branches. Many years ago Hutton noted the 
gently-undulating high-level plateau near Thames, which he considered to 
have been formed when the land was about 1,600 ft. lower than at present 
(6, p. 23). At Hicks Bay fossiliferous sands and muds form wide terraces 
which extend inland най seven ог eight miles and rise from 350 ft. to 650 ft. 
above the sea. Between Te Araroa and East Cape are gravel-veneered 
wave-cut benches aim 870 ft. to 1,000 ft. high.

The slight uplift, the effects of which farther north have been men- 
tioned, also raised the coast from East Cape to Wellington. Marine

Graton observed a series of beaches near Wellington respectively 4 ft.,
