in a letter, challenging him to fight, then in April 1864 moved closer to the British base to occupy to a new ridge-top position at Pukehinahina, a locality known to Europeans as "The Gate" because of the presence of a post-and-rail fence and gateway used by Māori to block Pākehā trespassers. The new fortification, which became known as the "Gate Pā", was built just 5 km from imperial troops, who were prohibited by Grey's orders from intervening. Puhirake, finding it increasingly difficult to keep his force together without a battle in prospect, again attempted to goad the British into action. Meanwhile, fighting had already broken out nearby. A large contingent of East Coast Māori, possibly as many as 700 warriors, were making their way towards the conflict at Waikato. Their route took them through the territory of another tribe which saw themselves as allies of the Pākehā, the Arawa tribe based around Rotorua. Forewarned of this, the Arawa chiefs called back their tribesmen, many of whom were working in Auckland or further north. Pausing in Tauranga to borrow guns from the British, they hastened onward to Rotorua. Four hundred warriors of the tribe were mobilised and they met and held the East Coast Māori on 7 April in a two-day battle on the shores of Lake Rotoiti. On 27 April fighting broke out again on the coast, with Māori loyal to the Crown supported by the 43rd Regiment and British corvettes firing on Kingite Māori as they were pursued through the sand dunes. Battle of Gate Pā Still hoping to provoke an attack, the 250 Ngāi Te Rangi fighters at Pukehinahina enlarged the existing trench and banks and transformed the pā into a system of two redoubts, including a honeycomb of rua, or anti-artillery bunkers. Ngāi Te Rangi garrisoned the main redoubt, and about 30 members of the Ngāti Koheriki hapu and another 10 men from Piri-Rikau and other hapu manned the smaller redoubt. With timber scarce in surrounding swampland, palisading was frail, but the location of the redoubt on a hilltop, and the total span of the palisading gave their enemy the impression of greater strength than it actually possessed. In all, the total garrison of Gate Pā was about 230 men. On 5 April Cameron abandoned hope of pursuing Ngāti Hauā leader and prominent Kingite Wiremu Tamihana after his foe evacuated the besieged Te Tiki o te Ihingarangi
