Hakarimata Range

Although now usually applied to the hills immediately west of Ngāruawāhia,[6] maps such as Hochstetter's of 1859,[7] the 1925 geology map[8] and 1944 one inch map show 'Hakarimata Range' as extending south to what is now SH23.[9] Similarly, old accounts describe the Whatawhata-Raglan road as passing over the Hakarimatas.[10]

Hakarimata's name derives from a 17th-century feast, when Ngāti Maniapoto joined the localWaikatos to celebrate the birth of a child. There was a mountain of raw forest foods; hence the name Hākari-kai-mata (uncooked food mountain), condensed to Hakarimata.[11]

Hakarimata is part of the roughly north - south Kawhia Syncline (Taupiri to the north, Kapamahunga to the south), though the Hakarimata Anticline is at about a 30° angle to the rest of the syncline, probably due to strike slip movement along the Waipa Fault,[12] Late Triassic Newcastle Group,[13] sandstones, siltstones and greywacke have been folded, faulted and covered by other sedimentary rocks to form the Hakarimatas.[3]

Since the land was reserved (from 1905 onwards), the fringe areas and lower slopes have slowly regenerated after suffering light logging, fires, pigs, goats, possums, cats, hedgehogs, rats, mice, stoats, weasels and ferrets, with occasional deer and wallaby. Goats, possum and rats are controlled,[3] with possum self-resetting traps trialled in 2011.[16] About 200 ha (490 acres) of privately owned forest adjoin the reserve, some of which is protected by covenant. Kauri dieback disease[3] is not present, so a boot cleaning station was put at the Huntly end in 2015.[17]

Fire is also a threat. In 2017 an area of 600 by 300m on a ridge beside the quarry was burnt.[18]

The large quarry at 181 Waingaro Road, Ngāruawāhia,[19] opened in a quarry reserve[20] in 1948[21] and now goes well below sea-level.[22] It was bought by Brian Perry Ltd in the 1980s[23] and sold to Fulton Hogan in 2016.[24][25] An extension which would have doubled the size of the quarry[21] wasn't permitted in 2008.[26][27] It would have taken native trees estimated to be 800 years old. The quarry then employed 13 and supplied about 35% of the area's needs.[21] Environment Waikato granted Perry Aggregates resource consents in 2009,[28] following which bait stations were put in the area in 2011[29] and the quarry was given Mimico Environmental Awards for that[30] and, in 2018, for extending native fish passage.[31]

The range has been used for recreational rambling since at least 1892.[32]

There are two main walkways through the range, allowing excellent views of the Waikato Plains below. The main one is Hakarimata Walkway (12 km, 7 hr 30 min) along the ridge from Parker Road at the northern end to the Hakarimata Rail Trail (off Waingaro Rd) at the south.[3]

Te Araroa follows that walkway to the summit,[33] where a viewing tower offers vistas towards the coast, across the Waikato Basin and to Ruapehu on a clear day.[3] Te Aroroa drops from the summit by the other main walkway, Hakarimata Summit Track[33] (2 km, 3 hr return, 335 metres on 1349 steps), to Brownlee Avenue in Ngāruawāhia.[3] The steps had 140,000 visits in 2016, compared to 5000 in 2011, shortly after they opened.[34] The remainder of the track south to Hakarimata Rail Trail (3.5 km, 2 hr) can be linked by a 1.8 km walk along Waingaro Road back to Brownlee Ave.[3]

There are several shorter walks using parts of the Hakarimata Walkway and/or the Summit Track:-

• At the northern end, Kauri Loop Track (3 km, 2 hr return for full loop; 40 min to kauri grove) from Parker Road car park starts with a long flight of steps to one of the largest kauris in Waikato,[3] 7 m (23 ft) girth and 36.7 m (120 ft) high,[35] estimated to be over a thousand years old. The Southern Lookout has views of Huntly and the north Waikato lakes, Hamilton and Tongariro on a clear day.[3]
• In the middle, Waterworks Walk (1 km, 1 hr return) from Brownlee Avenue runs beside Mangarata Stream to the 1922 reservoir, once Ngāruawāhia's water supply.[3] In November 2016 a Tomokanga (archway)[36] was added near the beginning of the walk.[13]
• At the southern end, Hakarimata Rail Trail (1.5 km, 30 min) follows the former Glen Massey railway.[3] A short extension leads to the Cascades.
