Sir Clive Woodward's Lions kick-off the New Zealand tour on Saturday, June 4 (8.10am Irish time), with a tie against Bay of Plenty at the Rotorua International Stadium.
Bay of Plenty, known as "the Steamers", and inspired by three tries from speedy Fijian winger Filimone Bolavucu, claimed a 43-15 victory over Poverty Bay in a representative "warm-up" game at Gisborne's Rugby Park earlier today.
Rotorua, a Maori heartland, will also act as the venue next Sunday, at which the Lions will be officially welcomed to New Zealand.
The Lions last toured New Zealand in 1993 when they lost the series 2-1, with the touring side's only series success on All-Black soil coming in 1971. Wales' John Dawes skippered and the legendary Carwyn James, also from Wales, managed back then, with the following Irish players involved: Mike Gibson (Centre) (North of Ireland/Ireland), Mike Hipwell (Number 8) (Terenure College/Ireland), Sean Lynch (Prop) (St Mary's College/Ireland), Willie John McBride (Lock) (Ballymena/Ireland), Ray McLoughlin (Prop) (Blackrock College/Ireland), Fergus Slattery (University College Dublin/Ireland).
The Lions' flight is due to touch down in Auckland, the biggest city in New Zealand with 1.5 million residents, at midday local time (01.00am Irish time) on Friday.
Graham Henry's extended All-Blacks squad, meanwhile, will take part in a "Probables v Possibles" trial match in Napier on Friday, June 3, and seven days later, they take on Fiji in a Test match in Albany.
There is also the little matter of the Super 12 final, involving the Crusaders and the Waratahs, this coming Saturday.
