Saying something did not happen

I tunu ahau i te keke.
I cooked the cake.

I peka atu a Pita ki te kāinga o tōna hoa.
Peter dropped in to his friend’s place.

I tango ahau i aku hū.
I removed my shoes.

I tāhae tōna hoa i taku pene.
His mate stole my pen

I āwhina atu ahau i taku māhita.
I helped out my teacher.

I haere taku māmā ki te toa.
My mum went to the store.

I kite a Mīria i a Hone i te pō whakangahau.
Milly saw John at the concert.

I waiata ia ināpō.
He/She sang last night.
