Acceleration on Water Festival of Speed
Not for those wanting a peaceful water day, this is world class powerboat racing: Grand Prix hydroplanes, Formula One tunnels, V8 racing runabouts, wake boarding, thunder cats, water ski and, um, bath tub racing. Or bring your lawnmower (let's face it, when did it last get an outing) for the on-shore lawnmower race. Kids can do the whole giant water slide, model boats and fly board X thing. You can even camp there.
Details: Saturday and Sunday, 11am to 3pm. Lake Karapiro, Maungatautari Rd, Cambridge. Tickets: Adults $15, under 13s free. More info here.
