Outstanding young batsman Tim Seifert has done it again.

The Year 13 St Peter's School student hit another quick-fire double century for his team when the Waikato secondary school competition resumed on Saturday.

In November last year Seifert struck an unbeaten 217 on his home ground against Hamilton Boys' High School Development, the school's highest score by an individual.

Now back after the summer break, which for Seifert included playing for Northern Districts at the national under-19 tournament, the runs keep blazing, the captain making 213 off 157 balls in his side's crushing 193-run one-day victory at home against St John's College.

Seifert hit 31 fours in his brilliant knock, and he has now scored centuries in his past five innings for the school against Waikato opposition.

Brandon Weal's 50 looked miserly in comparison to the attacking right-handed Seifert, who has all the shots in the book as well as the scoops and sweeps, as he got St Peter's to a massive 354-4 in their 50 overs.

St Peter's spinners Lewi Hopkins and Neil Achary took four and three wickets apiece to help dismiss St John's for 161 in 36.5 overs.

The other two matches in the weekend's opening round were also one-sided.

St Paul's Collegiate thrashed HBHS Development by 178 runs.

Alistair Blackett's 67 paved the way for St Paul's to post 235 all out in 49 overs, before Guy Wilkins took 5-11 in eight overs to roll HBHS for only 58 in the 36th over.

At Matamata College the home side belted Cambridge High School by nine wickets. The visitors put on 40 for the first wicket, but despite Nick Bateman making a fine 48, Cambridge were bundled out for 99 in the 25th over, with debutant Blair Underwood claiming 4-20 off six overs.

Matamata had no trouble chasing down the target, winning by nine wickets in just 15.3 overs to retain the Dave Hoskin Trophy.
