England [Images] beat New Zealand [Images] by 50 runs at Christchurch on Thursday to complete a 2-0 series sweep of their two Twenty20 internationals.

- Scorecard

England followed up their 32-run win in Auckland on Tuesday with an even more emphatic victory to continue their perfect start to the two-month tour.

England captain Paul Collingwood [Images] smashed a half-century to help his team compile a healthy total of 193 for eight before the tourists restricted New Zealand to 143-8 in reply.

Collingwood blasted 54 off just 28 balls, including five boundaries and three sixes, and shared in a 102-run partnership with Owais Shah, who made a brisk 47.

The pair steered England to an healthy total after they had lost four wickets for 12 runs to slump to 76-4 in the ninth over.

New Zealand's hopes of winning disappeared quickly when they crashed to 94-7 in the 14th over.

Jamie How (31) and Kyle Mills (30 not out) both made useful scores but the home side, missing several key players including their skipper Daniel Vettori [Images] and all-rounder Jacob Oram [Images], were always too far behind to mount a reasonable challenge.

England opened their tour with back-to-back wins over Canterbury last weekend and have now won all four matches they have played.

They face New Zealand in Wellington on Saturday in the first of five one-day internationals before the teams square off in three tests next month.
